How do you decrease 800 by 39 percent?

Answer 1

Convert 39% to a decimal number by doing the following:

39% = 39/100 = 0.39

or

Move the decimal to the left two spaces to change percent to a decimal number.

39% = 0.39

Then do the following calculation:

800 - (800 x 0.39) = 488

or

800 x 0.39 = 312

800 - 312 = 488
