What is 24 Percent of 75?
24% of 75 = 18
Step by step
- Turn the percentage into a decimal: 24 ÷ 100 = 0.24
- Multiply: 0.24 × 75 = 18
How the answer is worked out
“Percent” means “per hundred”, so 24% is 24 out of every 100, or 0.24 as a decimal. Taking 24% of 75 means multiplying 75 by 0.24, which gives 18.
18 is the 24% share of 75. The remaining 76% is 57, and the two parts add back up to 75.
Why calculate this?
Taking a percentage of a number is how discounts, tips, tax and interest are worked out.
- Discounts: 24% off an item priced $75 saves $18, so you pay $57.
- Tips: a 24% tip on a bill of $75 is $18, so the total is $93.
- Interest: simple interest of 24% a year on $75 earns $18 in one year and $90 over five years.
- Tax: a sales tax of 24% on a price of $75 adds $18, so the price including tax is $93.
A quicker way
Use 10% and 1%: 10% of 75 is 7.5 and 1% is 0.75. 24% is 2 × 10% + 4 × 1% = 15 + 3 = 18.
Swap the numbers if that is easier: 24% of 75 is always the same as 75% of 24, because both are 24 × 75 ÷ 100.
Check the answer
Work backwards: 18 ÷ 75 × 100 = 24%. Getting 24% back shows the answer is right.
Rounding
Rounded to a whole number the result is 18, to one decimal place 18.0 and to two decimal places 18.00. 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: 5% of 83
- Turn the percentage into a decimal: 5 ÷ 100 = 0.05
- Multiply: 0.05 × 83 = 4.15
Common percentages of 75
10% of 75 is 7.5, 20% is 15, a quarter (25%) is 18.75, half (50%) is 37.5 and three quarters (75%) is 56.25. Knowing these makes it easy to estimate any other percentage of 75 in your head.
Adding and taking away 24%
Increasing 75 by 24% gives 93 and decreasing it by 24% gives 57. These do not cancel out: raising 75 by 24% and then lowering the result by 24% ends at 70.68, because the second 24% is taken of a bigger number.
Finding the original number
If 18 is 24% of something, divide by 0.24 to get it back: 18 ÷ 0.24 = 75. This is how you work out a price before tax or a full amount from a share of it.
