Final answer:
Ashley used 1/10 of a cup of frosting on each of the eight cupcakes after dividing the total frosting equally.
Step-by-step explanation:
To find how much frosting Ashley used on each cupcake, we need to divide the total amount of frosting used by the number of cupcakes. Ashley used 4/5 of a cup of frosting, and she divided it equally among 8 cupcakes. Ashley used 4/5 of a cup of frosting to decorate some cupcakes, and she distributed this amount equally among 8 cupcakes. To find out how much frosting she used on each cupcake, we divide the total amount of frosting by the number of cupcakes. Here's the calculation:
4/5 cup ÷ 8 cupcakes = 1/10 cup per cupcake.
This means that Ashley used 1/10 of a cup of frosting on each cupcake.
