What is 85 Percent of 11?
85% of 11 = 9.35
Step by step
- Turn the percentage into a decimal: 85 ÷ 100 = 0.85
- Multiply: 0.85 × 11 = 9.35
How the answer is worked out
“Percent” means “per hundred”, so 85% is 85 out of every 100, or 0.85 as a decimal. Taking 85% of 11 means multiplying 11 by 0.85, which gives 9.35.
9.35 is the 85% share of 11. The remaining 15% is 1.65, and the two parts add back up to 11.
Why calculate this?
Taking a percentage of a number is how discounts, tips, tax and interest are worked out.
- Discounts: 85% off an item priced $11 saves $9.35, so you pay $1.65.
- Tips: a 85% tip on a bill of $11 is $9.35, so the total is $20.35.
- Interest: simple interest of 85% a year on $11 earns $9.35 in one year and $46.75 over five years.
- Tax: a sales tax of 85% on a price of $11 adds $9.35, so the price including tax is $20.35.
A quicker way
Use 10% and 1%: 10% of 11 is 1.1 and 1% is 0.11. 85% is 8 × 10% + 5 × 1% = 8.8 + 0.55 = 9.35.
Swap the numbers if that is easier: 85% of 11 is always the same as 11% of 85, because both are 85 × 11 ÷ 100.
Check the answer
Work backwards: 9.35 ÷ 11 × 100 = 85%. Getting 85% back shows the answer is right.
Rounding
Rounded to a whole number the result is 9, to one decimal place 9.3 and to two decimal places 9.35. 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: 16% of 6
- Turn the percentage into a decimal: 16 ÷ 100 = 0.16
- Multiply: 0.16 × 6 = 0.96
Common percentages of 11
10% of 11 is 1.1, 20% is 2.2, a quarter (25%) is 2.75, half (50%) is 5.5 and three quarters (75%) is 8.25. Knowing these makes it easy to estimate any other percentage of 11 in your head.
Adding and taking away 85%
Increasing 11 by 85% gives 20.35 and decreasing it by 85% gives 1.65. These do not cancel out: raising 11 by 85% and then lowering the result by 85% ends at 3.0525, because the second 85% is taken of a bigger number.
Finding the original number
If 9.35 is 85% of something, divide by 0.85 to get it back: 9.35 ÷ 0.85 = 11. This is how you work out a price before tax or a full amount from a share of it.
