Question

The recipe for the cupcakes she is making needs 2/3 cups of flour. She realizes she only needs to make 3/4 of the recipe. How much flour will she need?

Answer 1

Since we are making only 3/4 of the recipe, we need to multiply the amount of ingredients by that fraction to reduce their amounts (since 3/4 is below 1 whole).

Since we we are multiplying fractions, we do not need to change denominators.

2/3 * 3/4 = let’s break this down to numerators and denominators to see it easier

2*3= 6 <— this is our new numerator

3*4= 12 <—this is our new denominator

let’s write out our new fraction

6/12 Can we reduce? Yes we can because there is a number than can go into both 6 and 12. Let’s use 6!

6/6= 1 <— our reduced numerator

12/6= 2 <— our reduced denominator

Now we’re ready to answer our question.Make sure you always reread the question to get the right units!

1/2 cups of flour
