How could u turn 5/20 into a percent

To convert  to a percent, you must convert it to a decimal first

Divide the numerator(top) by the denominator(bottom)

5÷20=.25

All percents are based off of "100%" so multiply .25 by 100(%) which is 25%

25% 

The only number less than 8 that can equal 12 would be 6, 36 is the dividend
