What is 80 Percent of 67?
80% of 67 = 53.6
Step by step
- Turn the percentage into a decimal: 80 ÷ 100 = 0.8
- Multiply: 0.8 × 67 = 53.6
How the answer is worked out
“Percent” means “per hundred”, so 80% is 80 out of every 100, or 0.8 as a decimal. Taking 80% of 67 means multiplying 67 by 0.8, which gives 53.6.
53.6 is the 80% share of 67. The remaining 20% is 13.4, and the two parts add back up to 67.
Why calculate this?
Taking a percentage of a number is how discounts, tips, tax and interest are worked out.
- Discounts: 80% off an item priced $67 saves $53.6, so you pay $13.4.
- Tips: a 80% tip on a bill of $67 is $53.6, so the total is $120.6.
- Interest: simple interest of 80% a year on $67 earns $53.6 in one year and $268 over five years.
- Tax: a sales tax of 80% on a price of $67 adds $53.6, so the price including tax is $120.6.
A quicker way
Use 10% and 1%: 10% of 67 is 6.7 and 1% is 0.67. 80% is 8 × 10% = 53.6 = 53.6.
Swap the numbers if that is easier: 80% of 67 is always the same as 67% of 80, because both are 80 × 67 ÷ 100.
Check the answer
Work backwards: 53.6 ÷ 67 × 100 = 80%. Getting 80% back shows the answer is right.
Rounding
Rounded to a whole number the result is 54, to one decimal place 53.6 and to two decimal places 53.60. 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 52
- Turn the percentage into a decimal: 16 ÷ 100 = 0.16
- Multiply: 0.16 × 52 = 8.32
Common percentages of 67
10% of 67 is 6.7, 20% is 13.4, a quarter (25%) is 16.75, half (50%) is 33.5 and three quarters (75%) is 50.25. Knowing these makes it easy to estimate any other percentage of 67 in your head.
Adding and taking away 80%
Increasing 67 by 80% gives 120.6 and decreasing it by 80% gives 13.4. These do not cancel out: raising 67 by 80% and then lowering the result by 80% ends at 24.12, because the second 80% is taken of a bigger number.
Finding the original number
If 53.6 is 80% of something, divide by 0.8 to get it back: 53.6 ÷ 0.8 = 67. This is how you work out a price before tax or a full amount from a share of it.
