Understanding 10 Percent

Before diving into the shortcut, let's understand what 10 percent actually means. "Percent" simply means "out of one hundred." So, 10 percent is 10 out of every 100, or 10/100, which simplifies to 1/10. This simple fraction is the key to quick mental calculations.

The Easiest Way: Divide by 10

The fastest way to find 10 percent of a number is to divide that number by 10. This works because, as we just covered, 10% is equivalent to 1/10.

  • If the number ends in zero: Simply remove the zero. For example, 10% of 120 is 12.
  • If the number doesn't end in zero: Move the decimal point one place to the left. For example, 10% of 45 is 4.5, and 10% of 367 is 36.7.

  • What is 10% of 275? Answer: 27.5 (Move the decimal)
