What is the percent decrease from $25 to $10

Percent decrease=decrease/original

decrease=original-end

decrease=25-10=15

percent decrease=15/25=3/5

percent means parts out of 100

3/5=x%

3/5=x/100

times 100 both sides

300/5=x

60=x

answer is 60% decrease

60% because if you take 15$ from 25 then you can find how much % 15 is of 25
