What is 27 Percent of 4?
27% of 4 = 1.08
Step by step
- Turn the percentage into a decimal: 27 ÷ 100 = 0.27
- Multiply: 0.27 × 4 = 1.08
How the answer is worked out
“Percent” means “per hundred”, so 27% is 27 out of every 100, or 0.27 as a decimal. Taking 27% of 4 means multiplying 4 by 0.27, which gives 1.08.
1.08 is the 27% share of 4. The remaining 73% is 2.92, and the two parts add back up to 4.
Why calculate this?
Taking a percentage of a number is how discounts, tips, tax and interest are worked out.
- Discounts: 27% off an item priced $4 saves $1.08, so you pay $2.92.
- Tips: a 27% tip on a bill of $4 is $1.08, so the total is $5.08.
- Interest: simple interest of 27% a year on $4 earns $1.08 in one year and $5.4 over five years.
- Tax: a sales tax of 27% on a price of $4 adds $1.08, so the price including tax is $5.08.
A quicker way
Use 10% and 1%: 10% of 4 is 0.4 and 1% is 0.04. 27% is 2 × 10% + 7 × 1% = 0.8 + 0.28 = 1.08.
Swap the numbers if that is easier: 27% of 4 is always the same as 4% of 27, because both are 27 × 4 ÷ 100.
Check the answer
Work backwards: 1.08 ÷ 4 × 100 = 27%. Getting 27% back shows the answer is right.
Rounding
Rounded to a whole number the result is 1, to one decimal place 1.1 and to two decimal places 1.08. 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: 6% of 25
- Turn the percentage into a decimal: 6 ÷ 100 = 0.06
- Multiply: 0.06 × 25 = 1.5
Common percentages of 4
10% of 4 is 0.4, 20% is 0.8, a quarter (25%) is 1, half (50%) is 2 and three quarters (75%) is 3. Knowing these makes it easy to estimate any other percentage of 4 in your head.
Adding and taking away 27%
Increasing 4 by 27% gives 5.08 and decreasing it by 27% gives 2.92. These do not cancel out: raising 4 by 27% and then lowering the result by 27% ends at 3.7084, because the second 27% is taken of a bigger number.
Finding the original number
If 1.08 is 27% of something, divide by 0.27 to get it back: 1.08 ÷ 0.27 = 4. This is how you work out a price before tax or a full amount from a share of it.
