40 dolls to 15 dolls what is the percent of change increase or decrease

It wants us to find the percent of decrease.

First we find how much it is decreased, 40-15=25

Then we find out what percent is the 25(decreased amount) out of 40 by division.

25/40=5/8=0.625

25 is 0.625 of 40 which means that 15 is a 62.5% decrease from 40.

*Important: this problem is asking for the percent of decrease not the remaining percentage. This means that the answer is 62.5% instead of 37.5%
