What is 45 Percent of 46?
45% of 46 = 20.7
Step by step
- Turn the percentage into a decimal: 45 ÷ 100 = 0.45
- Multiply: 0.45 × 46 = 20.7
How the answer is worked out
“Percent” means “per hundred”, so 45% is 45 out of every 100, or 0.45 as a decimal. Taking 45% of 46 means multiplying 46 by 0.45, which gives 20.7.
20.7 is the 45% share of 46. The remaining 55% is 25.3, and the two parts add back up to 46.
Why calculate this?
Taking a percentage of a number is how discounts, tips, tax and interest are worked out.
- Discounts: 45% off an item priced $46 saves $20.7, so you pay $25.3.
- Tips: a 45% tip on a bill of $46 is $20.7, so the total is $66.7.
- Interest: simple interest of 45% a year on $46 earns $20.7 in one year and $103.5 over five years.
- Tax: a sales tax of 45% on a price of $46 adds $20.7, so the price including tax is $66.7.
A quicker way
Use 10% and 1%: 10% of 46 is 4.6 and 1% is 0.46. 45% is 4 × 10% + 5 × 1% = 18.4 + 2.3 = 20.7.
Swap the numbers if that is easier: 45% of 46 is always the same as 46% of 45, because both are 45 × 46 ÷ 100.
Check the answer
Work backwards: 20.7 ÷ 46 × 100 = 45%. Getting 45% back shows the answer is right.
Rounding
Rounded to a whole number the result is 21, to one decimal place 20.7 and to two decimal places 20.70. 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: 9% of 66
- Turn the percentage into a decimal: 9 ÷ 100 = 0.09
- Multiply: 0.09 × 66 = 5.94
Common percentages of 46
10% of 46 is 4.6, 20% is 9.2, a quarter (25%) is 11.5, half (50%) is 23 and three quarters (75%) is 34.5. Knowing these makes it easy to estimate any other percentage of 46 in your head.
Adding and taking away 45%
Increasing 46 by 45% gives 66.7 and decreasing it by 45% gives 25.3. These do not cancel out: raising 46 by 45% and then lowering the result by 45% ends at 36.685, because the second 45% is taken of a bigger number.
Finding the original number
If 20.7 is 45% of something, divide by 0.45 to get it back: 20.7 ÷ 0.45 = 46. This is how you work out a price before tax or a full amount from a share of it.
