What is 47 Percent of 20?
47% of 20 = 9.4
Step by step
- Turn the percentage into a decimal: 47 ÷ 100 = 0.47
- Multiply: 0.47 × 20 = 9.4
How the answer is worked out
“Percent” means “per hundred”, so 47% is 47 out of every 100, or 0.47 as a decimal. Taking 47% of 20 means multiplying 20 by 0.47, which gives 9.4.
9.4 is the 47% share of 20. The remaining 53% is 10.6, and the two parts add back up to 20.
Why calculate this?
Taking a percentage of a number is how discounts, tips, tax and interest are worked out.
- Discounts: 47% off an item priced $20 saves $9.4, so you pay $10.6.
- Tips: a 47% tip on a bill of $20 is $9.4, so the total is $29.4.
- Interest: simple interest of 47% a year on $20 earns $9.4 in one year and $47 over five years.
- Tax: a sales tax of 47% on a price of $20 adds $9.4, so the price including tax is $29.4.
A quicker way
Use 10% and 1%: 10% of 20 is 2 and 1% is 0.2. 47% is 4 × 10% + 7 × 1% = 8 + 1.4 = 9.4.
Swap the numbers if that is easier: 47% of 20 is always the same as 20% of 47, because both are 47 × 20 ÷ 100.
Check the answer
Work backwards: 9.4 ÷ 20 × 100 = 47%. Getting 47% back shows the answer is right.
Rounding
Rounded to a whole number the result is 9, to one decimal place 9.4 and to two decimal places 9.40. 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: 10% of 24
- Turn the percentage into a decimal: 10 ÷ 100 = 0.1
- Multiply: 0.1 × 24 = 2.4
Common percentages of 20
10% of 20 is 2, 20% is 4, a quarter (25%) is 5, half (50%) is 10 and three quarters (75%) is 15. Knowing these makes it easy to estimate any other percentage of 20 in your head.
Adding and taking away 47%
Increasing 20 by 47% gives 29.4 and decreasing it by 47% gives 10.6. These do not cancel out: raising 20 by 47% and then lowering the result by 47% ends at 15.582, because the second 47% is taken of a bigger number.
Finding the original number
If 9.4 is 47% of something, divide by 0.47 to get it back: 9.4 ÷ 0.47 = 20. This is how you work out a price before tax or a full amount from a share of it.
