The fastest way to take 20 percent off a number is to multiply the original number by 0.8 20% of 30 is 6. 30 - 6 = 24 30 x 0.8 = 24
First, you convert 20 percent into a decimal, by moving it to the left twice. 20% = .20 Then, you multiply 24 by .20 24 x .20 = 4.8 20 percent off 24 is 4.8. Hope I helped!
