Lourdes are 5/6 of a brownie. Zachary are 4/5 of a brownie of the same size. Who are more brownies?

OleMash [197]

Answer:

Lourdes has more brownies.

Step-by-step explanation:

First, you have to find a common denominator. Whatever you do to the bottom of the fraction you do to the top. 5/6 and 4/5 has a common denominator of 30. Multiply both digits in 5/6 by 5. Then multiply both digits in 4/5 by 6. Then you can compare the fractions. With the common denominators, Lourdes should have 25/30 brownies and Zachary has 24/30. Compare.

24/30 < 25/30. So Lourdes has the most brownies!
