Question

James gave Robert half a candy bar. Robert gave his sister half of what he had. What fraction of the whole candy bar did Robert Sister get? What percent of the candy bar did she get

Answer 1

1/4

25%

Explanation:

Robert has 1/2 of the candy bar

If he gave his sister half, she has 1/2 x 1/2 = 1/4 of the candy bar

To convert 1/4 to percentage, multiply by 100

1/4 x 100 = 25%
