At Halloween 3/10 of the candy Robin received was chocolate. What percent of the candy was chocolate?

30%

Step-by-step explanation:

Percent means out of 100

We need to get the fraction out of 100, so multiply the top and bottom by 10

3/10 *10/10

30/100

The fraction is 30%

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
