Question

A recipe uses 2/3 cup of flour and 5/8 cup of blueberries. Is there more flour or more blueberries in the recipe?

Answer 1

flour has more because flour has 16/24 and blueberries has 15/24

Answer 2

This can be solved by converting both fractions to a common denominator. The easiest way to find a common denominator is to multiply both denominators together. So, 3*8 is 24.

Next, convert the numerators. Multiply the numerator of each fraction by the old denominator of the other fraction.

Flour:

2/3 -> (2*8)/24 -> 16/24

Blueberries:

5/8 -> (5*3)/24 -> 15/24
------
Because the numerator of flour, 16, is greater than that of blueberries, 15, and both fractions have the same denominator, the amount of flour is greater than the amount of blueberries in the recipe.
