What is 12 Percent of 13?
12% of 13 = 1.56
Step by step
- Turn the percentage into a decimal: 12 ÷ 100 = 0.12
- Multiply: 0.12 × 13 = 1.56
How the answer is worked out
“Percent” means “per hundred”, so 12% is 12 out of every 100, or 0.12 as a decimal. Taking 12% of 13 means multiplying 13 by 0.12, which gives 1.56.
1.56 is the 12% share of 13. The remaining 88% is 11.44, and the two parts add back up to 13.
Why calculate this?
Taking a percentage of a number is how discounts, tips, tax and interest are worked out.
- Discounts: 12% off an item priced $13 saves $1.56, so you pay $11.44.
- Tips: a 12% tip on a bill of $13 is $1.56, so the total is $14.56.
- Interest: simple interest of 12% a year on $13 earns $1.56 in one year and $7.8 over five years.
- Tax: a sales tax of 12% on a price of $13 adds $1.56, so the price including tax is $14.56.
A quicker way
Use 10% and 1%: 10% of 13 is 1.3 and 1% is 0.13. 12% is 1 × 10% + 2 × 1% = 1.3 + 0.26 = 1.56.
Swap the numbers if that is easier: 12% of 13 is always the same as 13% of 12, because both are 12 × 13 ÷ 100.
Check the answer
Work backwards: 1.56 ÷ 13 × 100 = 12%. Getting 12% back shows the answer is right.
Rounding
Rounded to a whole number the result is 2, to one decimal place 1.6 and to two decimal places 1.56. Round only at the end: rounding halfway through a calculation can change the last digit.
The formula explained
result = percentage ÷ 100 × number. Dividing the percentage by 100 turns it into a decimal multiplier, so 25% becomes 0.25 and 150% becomes 1.5. Multiplying the number by that decimal gives the share.
Another worked example: 3% of 5
- Turn the percentage into a decimal: 3 ÷ 100 = 0.03
- Multiply: 0.03 × 5 = 0.15
Common percentages of 13
10% of 13 is 1.3, 20% is 2.6, a quarter (25%) is 3.25, half (50%) is 6.5 and three quarters (75%) is 9.75. Knowing these makes it easy to estimate any other percentage of 13 in your head.
Adding and taking away 12%
Increasing 13 by 12% gives 14.56 and decreasing it by 12% gives 11.44. These do not cancel out: raising 13 by 12% and then lowering the result by 12% ends at 12.8128, because the second 12% is taken of a bigger number.
Finding the original number
If 1.56 is 12% of something, divide by 0.12 to get it back: 1.56 ÷ 0.12 = 13. This is how you work out a price before tax or a full amount from a share of it.
