last month john spent 75.00 dollars on games. this month he only spent 63.00. he spent ___ percent less this month

aivan3 [116]

First, subtract 63 from 75 to find out how much it decreased.
75 - 63 = 12
Divide 12 by 75.
12 / 75 = 0.16
In percents, that is 16%.
He spent 16% less this month.
Hope this helps!
