What is 12 Percent of 85?
12% of 85 = 10.2
Step by step
- Turn the percentage into a decimal: 12 ÷ 100 = 0.12
- Multiply: 0.12 × 85 = 10.2
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 85 means multiplying 85 by 0.12, which gives 10.2.
10.2 is the 12% share of 85. The remaining 88% is 74.8, and the two parts add back up to 85.
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 $85 saves $10.2, so you pay $74.8.
- Tips: a 12% tip on a bill of $85 is $10.2, so the total is $95.2.
- Interest: simple interest of 12% a year on $85 earns $10.2 in one year and $51 over five years.
- Tax: a sales tax of 12% on a price of $85 adds $10.2, so the price including tax is $95.2.
A quicker way
Use 10% and 1%: 10% of 85 is 8.5 and 1% is 0.85. 12% is 1 × 10% + 2 × 1% = 8.5 + 1.7 = 10.2.
Swap the numbers if that is easier: 12% of 85 is always the same as 85% of 12, because both are 12 × 85 ÷ 100.
Check the answer
Work backwards: 10.2 ÷ 85 × 100 = 12%. Getting 12% back shows the answer is right.
Rounding
Rounded to a whole number the result is 10, to one decimal place 10.2 and to two decimal places 10.20. 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 18
- Turn the percentage into a decimal: 3 ÷ 100 = 0.03
- Multiply: 0.03 × 18 = 0.54
Common percentages of 85
10% of 85 is 8.5, 20% is 17, a quarter (25%) is 21.25, half (50%) is 42.5 and three quarters (75%) is 63.75. Knowing these makes it easy to estimate any other percentage of 85 in your head.
Adding and taking away 12%
Increasing 85 by 12% gives 95.2 and decreasing it by 12% gives 74.8. These do not cancel out: raising 85 by 12% and then lowering the result by 12% ends at 83.776, because the second 12% is taken of a bigger number.
Finding the original number
If 10.2 is 12% of something, divide by 0.12 to get it back: 10.2 ÷ 0.12 = 85. This is how you work out a price before tax or a full amount from a share of it.
