Membership in the fishing club went from 120 members last year to 87 members this year. What was the percent of decrease in membership? What was the amount of change from 120 members to 87 members?

1. To calculate percentage decrease:

First: look for the difference (decrease) between the two numbers you are equating. Decrease = 120 - 87 = 33

Then: divide the decrease by the original number and multiply the answer by 100.% Decrease = 33 : 120 * 100 = 0.275 x 100 = 27.5% or 28%

2. We have a decrease of 33 which is the amount of change.
