Question

During a weight loss challenge your friend goes from 125pounds to 100 pounds. What was the percent weight loss ?

Answer 1

percent change=change/original times 100
change=125-100=25
original=125


percent change=25/125 times 100
percent change=1/5 times 100
percent change=0.20 times 100
percent change=20%


answer is 20%

Answer 2

percent decrease = (original number - new number) / original number....x 100
percent decrease : (125 - 100) / 125....x 100
                                25/125 = 0.2......x 100 = 20% decrease
