What is 59 Percent of 42?
59% of 42 = 24.78
Step by step
- Turn the percentage into a decimal: 59 ÷ 100 = 0.59
- Multiply: 0.59 × 42 = 24.78
How the answer is worked out
“Percent” means “per hundred”, so 59% is 59 out of every 100, or 0.59 as a decimal. Taking 59% of 42 means multiplying 42 by 0.59, which gives 24.78.
24.78 is the 59% share of 42. The remaining 41% is 17.22, and the two parts add back up to 42.
Why calculate this?
Taking a percentage of a number is how discounts, tips, tax and interest are worked out.
- Discounts: 59% off an item priced $42 saves $24.78, so you pay $17.22.
- Tips: a 59% tip on a bill of $42 is $24.78, so the total is $66.78.
- Interest: simple interest of 59% a year on $42 earns $24.78 in one year and $123.9 over five years.
- Tax: a sales tax of 59% on a price of $42 adds $24.78, so the price including tax is $66.78.
A quicker way
Use 10% and 1%: 10% of 42 is 4.2 and 1% is 0.42. 59% is 5 × 10% + 9 × 1% = 21 + 3.78 = 24.78.
Swap the numbers if that is easier: 59% of 42 is always the same as 42% of 59, because both are 59 × 42 ÷ 100.
Check the answer
Work backwards: 24.78 ÷ 42 × 100 = 59%. Getting 59% back shows the answer is right.
Rounding
Rounded to a whole number the result is 25, to one decimal place 24.8 and to two decimal places 24.78. 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: 12% of 4
- Turn the percentage into a decimal: 12 ÷ 100 = 0.12
- Multiply: 0.12 × 4 = 0.48
Common percentages of 42
10% of 42 is 4.2, 20% is 8.4, a quarter (25%) is 10.5, half (50%) is 21 and three quarters (75%) is 31.5. Knowing these makes it easy to estimate any other percentage of 42 in your head.
Adding and taking away 59%
Increasing 42 by 59% gives 66.78 and decreasing it by 59% gives 17.22. These do not cancel out: raising 42 by 59% and then lowering the result by 59% ends at 27.3798, because the second 59% is taken of a bigger number.
Finding the original number
If 24.78 is 59% of something, divide by 0.59 to get it back: 24.78 ÷ 0.59 = 42. This is how you work out a price before tax or a full amount from a share of it.
