What is 11 Percent of 27?
11% of 27 = 2.97
Step by step
- Turn the percentage into a decimal: 11 ÷ 100 = 0.11
- Multiply: 0.11 × 27 = 2.97
How the answer is worked out
“Percent” means “per hundred”, so 11% is 11 out of every 100, or 0.11 as a decimal. Taking 11% of 27 means multiplying 27 by 0.11, which gives 2.97.
2.97 is the 11% share of 27. The remaining 89% is 24.03, and the two parts add back up to 27.
Why calculate this?
Taking a percentage of a number is how discounts, tips, tax and interest are worked out.
- Discounts: 11% off an item priced $27 saves $2.97, so you pay $24.03.
- Tips: a 11% tip on a bill of $27 is $2.97, so the total is $29.97.
- Interest: simple interest of 11% a year on $27 earns $2.97 in one year and $14.85 over five years.
- Tax: a sales tax of 11% on a price of $27 adds $2.97, so the price including tax is $29.97.
A quicker way
Use 10% and 1%: 10% of 27 is 2.7 and 1% is 0.27. 11% is 1 × 10% + 1 × 1% = 2.7 + 0.27 = 2.97.
Swap the numbers if that is easier: 11% of 27 is always the same as 27% of 11, because both are 11 × 27 ÷ 100.
Check the answer
Work backwards: 2.97 ÷ 27 × 100 = 11%. Getting 11% back shows the answer is right.
Rounding
Rounded to a whole number the result is 3, to one decimal place 3.0 and to two decimal places 2.97. 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 79
- Turn the percentage into a decimal: 3 ÷ 100 = 0.03
- Multiply: 0.03 × 79 = 2.37
Common percentages of 27
10% of 27 is 2.7, 20% is 5.4, a quarter (25%) is 6.75, half (50%) is 13.5 and three quarters (75%) is 20.25. Knowing these makes it easy to estimate any other percentage of 27 in your head.
Adding and taking away 11%
Increasing 27 by 11% gives 29.97 and decreasing it by 11% gives 24.03. These do not cancel out: raising 27 by 11% and then lowering the result by 11% ends at 26.6733, because the second 11% is taken of a bigger number.
Finding the original number
If 2.97 is 11% of something, divide by 0.11 to get it back: 2.97 ÷ 0.11 = 27. This is how you work out a price before tax or a full amount from a share of it.
