Why do we need to add and subtract fractions with like denominators in real life?
There are so many reasons why do we need to add and subtract fractions with like denominators in real life?
For instance we all know pizza and fractions go well together. Now imagine you ordered 8 slices of pepperoni pizza as well as 8 slices of mushroom pizza. After eating 5/8 and 6/8 of the respective types of pizza with your family and there are left overs, how will you calculate the total quantity of the left overs?
Also, given that you need to know the total quantity of left over pizzas to determine if they can be fitted in a box that takes just 8 slices, you’ll be required to definitely add up the two fractions of the pizzas.
And of course, you’ll be adding two fractions with like denominators which imply adding just the numerators, then place the result over the common denominator.
