Question

My sister baked me a cake. We bought a litre of milk and went to town - we almost ate the whole cake! In the end my sister and I ate 5/7 of the cake. If the remainder of the cake was divided among three other friends (not including me and my sister) how much would each friend receive?

Answer 1

2/21

Explanation:

2/7 ÷3

sorry if wrong

2/7 * 1/3

2/21

Answer 2

2/21 per friend

Explanation:

A whole cake is 1 or as a fraction 7/7

5/7 of the cake was eaten

7/7 - 5/7 = 2/7

This was divided by 3 friends

2/7 ÷3

Copy dot flip

2/7 * 1/3

2/21
