   75 ÷ 100 = 0.75
2. Multiply by the original number: Multiply 64 by the decimal to find out exactly how much “75%” is in real numbers.
   64 × 0.75 = 48
3. Subtract that value from the original number: Take your 48 and subtract it from the starting 64.
   64 − 48 = 16

Therefore, decreasing 64 by 75 percent results in exactly 16.
