Question

Erin needs 4 5 of a cup of chocolate chips to make a cake and 1 2 of a cup of chocolate chips for the frosting. She's trying to decide if a one cup bag of chocolate chips will be enough for the cake and the frosting. Determine whether Erin needs to buy more chocolate chips.

Answer 1

Yes, she needs to buy more

Explanation:

4/5 + 1/2 = 8/10 + 5/10 = 13/10 cups of chocolate needed

13/10 > 10/10

13/10-10/10 = 3/10

she needs 3/10 cup of chocolate more
