Question

Gary and Joey share a 16-ounce box of cereal. By the end of the week, Gary has eaten 3/8 of the box, and Joey has eaten 1/4 of the box of cereal. How many ounces are left in the box?

Answer 1

Let’s start by converting the fractions into percentages.
1/4=25%
3/8=37.5%
25% of 16= 4
37.5% of 16= 6
4 + 6 = 10
16 - 10 = 6
Answer: 6 ounces

Answer 2

3/8 of the box is left so 6 ounces is left.

Explanation:

Make the 1/4, 2/8 then add 2/8 by 3/8 to get 5/8 then subtract 8/8 by 5/8 to get 3/8 then multiply it by 2 to get 6/16.

So the answer is 6/16 or 6.
