What is 62 Percent of 30?
62% of 30 = 18.6
Step by step
- Turn the percentage into a decimal: 62 ÷ 100 = 0.62
- Multiply: 0.62 × 30 = 18.6
How the answer is worked out
“Percent” means “per hundred”, so 62% is 62 out of every 100, or 0.62 as a decimal. Taking 62% of 30 means multiplying 30 by 0.62, which gives 18.6.
18.6 is the 62% share of 30. The remaining 38% is 11.4, and the two parts add back up to 30.
Why calculate this?
Taking a percentage of a number is how discounts, tips, tax and interest are worked out.
- Discounts: 62% off an item priced $30 saves $18.6, so you pay $11.4.
- Tips: a 62% tip on a bill of $30 is $18.6, so the total is $48.6.
- Interest: simple interest of 62% a year on $30 earns $18.6 in one year and $93 over five years.
- Tax: a sales tax of 62% on a price of $30 adds $18.6, so the price including tax is $48.6.
A quicker way
Use 10% and 1%: 10% of 30 is 3 and 1% is 0.3. 62% is 6 × 10% + 2 × 1% = 18 + 0.6 = 18.6.
Swap the numbers if that is easier: 62% of 30 is always the same as 30% of 62, because both are 62 × 30 ÷ 100.
Check the answer
Work backwards: 18.6 ÷ 30 × 100 = 62%. Getting 62% back shows the answer is right.
Rounding
Rounded to a whole number the result is 19, to one decimal place 18.6 and to two decimal places 18.60. 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: 12% of 74
- Turn the percentage into a decimal: 12 ÷ 100 = 0.12
- Multiply: 0.12 × 74 = 8.88
Common percentages of 30
10% of 30 is 3, 20% is 6, a quarter (25%) is 7.5, half (50%) is 15 and three quarters (75%) is 22.5. Knowing these makes it easy to estimate any other percentage of 30 in your head.
Adding and taking away 62%
Increasing 30 by 62% gives 48.6 and decreasing it by 62% gives 11.4. These do not cancel out: raising 30 by 62% and then lowering the result by 62% ends at 18.468, because the second 62% is taken of a bigger number.
Finding the original number
If 18.6 is 62% of something, divide by 0.62 to get it back: 18.6 ÷ 0.62 = 30. This is how you work out a price before tax or a full amount from a share of it.
