What is 60 Percent of 45?
60% of 45 = 27
Step by step
- Turn the percentage into a decimal: 60 ÷ 100 = 0.6
- Multiply: 0.6 × 45 = 27
How the answer is worked out
“Percent” means “per hundred”, so 60% is 60 out of every 100, or 0.6 as a decimal. Taking 60% of 45 means multiplying 45 by 0.6, which gives 27.
27 is the 60% share of 45. The remaining 40% is 18, and the two parts add back up to 45.
Why calculate this?
Taking a percentage of a number is how discounts, tips, tax and interest are worked out.
- Discounts: 60% off an item priced $45 saves $27, so you pay $18.
- Tips: a 60% tip on a bill of $45 is $27, so the total is $72.
- Interest: simple interest of 60% a year on $45 earns $27 in one year and $135 over five years.
- Tax: a sales tax of 60% on a price of $45 adds $27, so the price including tax is $72.
A quicker way
Use 10% and 1%: 10% of 45 is 4.5 and 1% is 0.45. 60% is 6 × 10% = 27 = 27.
Swap the numbers if that is easier: 60% of 45 is always the same as 45% of 60, because both are 60 × 45 ÷ 100.
Check the answer
Work backwards: 27 ÷ 45 × 100 = 60%. Getting 60% back shows the answer is right.
Rounding
Rounded to a whole number the result is 27, to one decimal place 27.0 and to two decimal places 27.00. 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: 12% of 99
- Turn the percentage into a decimal: 12 ÷ 100 = 0.12
- Multiply: 0.12 × 99 = 11.88
Common percentages of 45
10% of 45 is 4.5, 20% is 9, a quarter (25%) is 11.25, half (50%) is 22.5 and three quarters (75%) is 33.75. Knowing these makes it easy to estimate any other percentage of 45 in your head.
Adding and taking away 60%
Increasing 45 by 60% gives 72 and decreasing it by 60% gives 18. These do not cancel out: raising 45 by 60% and then lowering the result by 60% ends at 28.8, because the second 60% is taken of a bigger number.
Finding the original number
If 27 is 60% of something, divide by 0.6 to get it back: 27 ÷ 0.6 = 45. This is how you work out a price before tax or a full amount from a share of it.
