Adding and Subtracting Fractions with Unlike Denominators Worksheets Pdf Grade 4
Comparing Fractions Worksheets 4th Grade
Easy guide to adding and subtracting fractions with unlike denominators worksheets pdf grade 4. Apart from simply adding and subtracting fractions with unlike denominators, we have endeavoured to cover a variety of fraction skills, such as comparing fractions worksheets grade 4, add and subtract mixed numbers with unlike denominators, find the missing numerator or denominator in addition and subtraction exercise, etc.
Kid’s ability to be flexible in adding and subtracting fractions with unlike denominators is our primary objective in this resource. So, we have initiated a good number of admirable strategies by using different contexts (word problems and recipes) and fun models.
As a result, these amazing strategies will provide a conceptual understanding and the importance of finding a common denominator.

Why the need for a common denominator when adding and subtracting fractions with unlike denominators?
There is always a need for a common denominator when adding and subtracting fractions with unlike denominator.
Even though it’s easy to add and subtract fractions with unlike denominators using models, it is equally very easy to solve this by first of all finding their common denominator.
How then do we find the common denominator?
To find the common denominator of two or more fractions, we’ll first of all;
Find the Least Common Multiple (LCM) of their denominators, i.e. the smallest number that is evenly divisible by all the denominators.
Example:
Let's solve the following expression: 5/6 + 1/3
We know that the LCM of 6 and 3 is 6.
 First, divide the LCM by the denominator of each fraction;
 Then, get the result;
 Finally, multiply by the numerator.
When the results of the fractions have been gotten, then you can now add or subtract those results normally to obtain your final answer.
Your new answer will now be the numerator, while the found LCM will be the denominator.
→ 5/6 + 1/3 = (5 + 2)/6 = 7/6
So, 5/6 + 1/3 = 7/6
