Mrs. Bailey had 15 pieces of candy. She gave away some candy and has 3 pieces left. What is the percent decrease of candy?

12

Step-by-step explanation:

subtract 15 away from 3 and you have 12 so that how Mrs. Bailey has 3 pieces of candy left

80% decrease

Step-by-step explanation:

Find out how much percent each candy is worth:

100/15 = 6.67%

Find out how many pieces she gave away:

15 - 3 = 12

Multiply the pieces gave away by the percent per piece:

12 x 6.67 = 80.04

Round to the nearest whole number.

When using a calculator for 100/15 and then multiply by 12 you get exactly 80.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
