### Multiple Choice Questions (MCQs) on operations on whole numbers for grade 6 answers and explanations

Here are multiple-choice questions (MCQs) on operations on whole numbers for grade 6 answers and explanations to help students/children to verify their work and get a better understanding of the given exercises.

Question 1:

The correct answer is B) 810.

To solve this problem, you can use the associative property of addition and subtraction, which states that you can group the numbers in any way without changing the result.

For example, you can rewrite the expression as (567 - 99) + 432, which gives 468 + 432 = 810.

Question 2:

The correct answer is A) 578.

To solve this problem, you need to apply the order of operations, which states that you must perform the operations inside the parentheses before doing anything else.

So, you have to calculate 567 + 89 first and get 656. Then, you subtract that from 1234, which gives you 578.

Question 3:

To find the quotient of two numbers, you divide them. So 144 ÷ 12 = 12.

• Question 4:

The correct answer is A) 888. To solve this problem, we also need to follow the order of operations. First, we subtract 888 from 999, which gives us 111. Then, we add 777 to 111, which gives us 888.

Question 5:

To find the missing factor, you can use inverse operations. That means you can divide both sides of the equation by 9 to get the answer.

So ___ x 9 = 81 becomes ___ = 81 ÷ 9, which is ___ = 9.

Question 6:

To find the product of two numbers, you multiply them together. So 12 x 15 = 180.

Question 7:

The correct answer is B) 1112.

To solve this problem, we need to follow the order of operations.

First, we add 456 and 789, which gives us 1245. Then, we subtract 123 from 1245, which gives us 1112.

Question 8:

The correct answer is A) 5555.

To solve this problem, you can use a similar strategy as in question 2. So, you can first add (9999 + 1111) and (2222 + 3333), which makes it easier to solve.

Therefore the equation sentence becomes (11110 - 5555), which is equal to 5555.

Question 9:

To find the missing divisor, you can also use inverse operations. That means you can multiply both sides of the equation by ___ to get the answer.

So 72 ÷ ___ = 9 becomes 72 = ___ x 9, which means ___ = 72 ÷ 9. So, ___ = 8.

Question 10:

To evaluate this expression, you need to follow the order of operations. That means you do what's inside the parentheses first, then multiply or divide from left to right.

So (6 x 5) ÷ (3 x2 ) becomes (30) ÷ (6), which is equal to (10 ÷3).

### Writing Whole Numbers in Words Complete with the Missing Word Exercises for Grade 6

These Class 6 operations on whole numbers word problems with answers and explanations contain multiple real-life situations which involve addition, subtraction, multiplication, and division of whole numbers for grade 6. These problems will help your students/children to practice their arithmetic skills and also test their logical thinking.

#### Problem 1:

Alice has 12 books in her backpack and 8 books on her desk. She wants to donate some of her books to the school library. She decides to donate half of the books in her backpack and a quarter of the books on her desk. How many books will Alice have left after donating?

• Solution:

To find out how many books Alice will have left, we must subtract the number of books she donated from the total number of books she had.

First, let's find out how many books she donated from her backpack and desk.

Half of 12 books is 12 ÷ 2 = 6 books.

A quarter of 8 books is 8 ÷ 4 = 2 books.

So, Alice donated 6 + 2 = 8 books in total.

Secondly, let's find out how many books Alice had before donating. We add the number of books in her backpack and on her desk to get it.

12 + 8 = 20 books.

Finally, let's find the remaining number of books after the donation. To get it, we subtract the number of books donated from the total number of books she had.

20 - 8 = 12 books.

Therefore, Alice will have 12 books left after donating.

#### Problem 2:

Ben and his friends are playing a game of bowling. Ben scores 135 points in the first round and 120 points in the second round. His friend Sam scores 145 points in the first round and 110 points in the second round. How many more points does Ben score than Sam in total?

To find out how many more points Ben scores than Sam in total, we need to add up their scores for both rounds and then subtract them.

Ben's total score = 135 + 120 = 255

Sam's total score = 145 + 110 = 255

Ben's total score - Sam's total score = 255 - 255 = 0

Therefore, Ben and Sam score the same number of points in total.

#### Problem 3:

Leona is making cookies for a bake sale. She has a recipe that makes 24 cookies using 3 cups of flour, 2 cups of sugar, and 1 cup of butter. She wants to make 72 cookies for the bake sale. How many cups of each ingredient does she need?

To find out how many cups of each ingredient Leona needs, we need to multiply the quantity of each ingredient in the recipe by a factor that will give us 72 cookies. We know that the recipe makes 24 cookies, which means we need to multiply by 3, since 24 × 3 = 72.

Flour: 3 × 3 = 9 cups

Sugar: 2 × 3 = 6 cups

Butter: 1 × 3 = 3 cups

Therefore, Leona needs 9 cups of flour, 6 cups of sugar, and 3 cups of butter to make 72 cookies.

#### Problem 4:

Andy collects postcards. Currently, he has 360 postcards that he wants to share with 11 siblings. How many postcards will each person get?

Solution:

To find out how many postcards each person will get, we need to divide the total number of postcards by the number of people.

360 ÷ 12 = 30

Therefore, each person will get 30 postcards.

### Sixth-grade operations on whole numbers multi-step word problems with explanations

All that we have done up there are very interesting, but what if we go deep through our topic with this sixth-grade operations on whole numbers multi-step word problems with explanations?

Because we need to practice addition, subtraction, multiplication, and division, we will solve this long word problem which resumes all arithmetic operations correctly.

• #### Problem 5:

Bob wants to buy a new bike that costs \$240. He has saved up \$80 so far. He earns \$10 for every hour he works at his part-time job.

1. How long does Bob need to work to buy the bike?
2. Knowing that he can only get paid if he finishes a full hour, how many hours does Bob have to work to buy the bike and accessories worth \$148?
3. If, besides what he had saved, Bob works 4 hours a day for 9 days to buy the bike and its accessories, how much will he have left after his purchases?

Here is the explanation of how to solve the sixth-grade operations on whole numbers multi-step word problems.

To solve this first question, we must find out how much more money Bob needs to save and divide that amount by his hourly wage.

We know that Bob saved \$80. So, he is already own that amount.

To find out how much more money Bob needs, we must subtract the saved amount (\$80) from the bike price (\$240).

Therefore, Bob needs 240 - 80, which is equal to 160 more to buy the bike. So, \$160 is what he needs more for the purchase of the bike.

Now, we need to know the number of work hours required for him to earn \$160. To get it, we must divide \$160 by \$10, which is his hourly wage.

160 ÷ 10 = 16.

It means that Bob needs 16 hours of work to buy the bike.

For Bob to buy accessories worth \$148 and the bike, we must find how many hours he needs to work to earn money for accessories. Then, we will add that number of hours to the precedent one to find the total hours to work.

We begin with the number of work hours required for him to earn \$148.

To find it, we divide \$148, which is the cost of the accessories by 10, which represents the amount earned per hour.  The answer is: 148 ÷ 10 = 14r8

So, Bob needs to work 14 hours and one-eighth of an hour to earn \$148.

Since the work is paid per hour, he is supposed to work an overtime hour instead of one-eighth of an hour. Thus, he must work 15 hours to be able to buy the additional accessories.

Therefore, the time he needs to work to buy the bike and the accessories is 16 hours, which is the time he needs to work for the bike plus 15 hours, which is the time needed for the accessories.

16 + 15 = 31 hours.

So, Bob must work for 31 hours to buy the bike and accessories.

To solve this question, we need to find out how much money Bob earns from working, how much money he needs to buy the bike and its accessories, and how much money he has left after his purchases.

First, let's calculate how much money Bob earns from working. He works 4 hours a day for 9 days, so he works a total of 4 x 9 = 36 hours. He earns \$10 for every hour he works, so he earns a total of 10 x 36 = \$360 from working.

Next, let's calculate how much money Bob needs to buy the bike and its accessories. The bike costs \$240, and the accessories cost \$148. Thus, the total cost of the bike and its accessories is 240 + 148 = \$388.

Finally, let's calculate how much money Bob has left after his purchases. He has saved up \$80 and he earns \$360 from working, so he has a total of 80 + 360 = \$440 before his purchases. He spends \$388 on the bike and its accessories, so he has a remaining amount of 440 - 388 = \$52 after his purchases.

Therefore, Bob will have \$52 left after buying the bike and its accessories.
