The difference between the greatest and least amount of cupcake flavors is 0. 75
From the information given, we have that:
1/ 4 of cupcakes = chocolates
0. 2 of cupcakes = vanilla
Remaining = strawberry
Let the total number of cupcakes be 1
Strawberry = 1 - chocolates - vanilla
Strawberry = 1- 0. 25 - 0. 2
Strawberry = 1 - 0. 05
Strawberry = 0. 95
The difference between the greatest and least amount of cupcake flavors
= Strawberry cupcakes - Vanilla cupcakes
= 0. 95 - 0. 2
= 0. 75
Thus, the difference between the greatest and least amount of cupcake flavors is 0. 75
