What is 15 Percent of 49?
15% of 49 = 7.35
Step by step
- Turn the percentage into a decimal: 15 ÷ 100 = 0.15
- Multiply: 0.15 × 49 = 7.35
How the answer is worked out
“Percent” means “per hundred”, so 15% is 15 out of every 100, or 0.15 as a decimal. Taking 15% of 49 means multiplying 49 by 0.15, which gives 7.35.
7.35 is the 15% share of 49. The remaining 85% is 41.65, and the two parts add back up to 49.
Why calculate this?
Taking a percentage of a number is how discounts, tips, tax and interest are worked out.
- Discounts: 15% off an item priced $49 saves $7.35, so you pay $41.65.
- Tips: a 15% tip on a bill of $49 is $7.35, so the total is $56.35.
- Interest: simple interest of 15% a year on $49 earns $7.35 in one year and $36.75 over five years.
- Tax: a sales tax of 15% on a price of $49 adds $7.35, so the price including tax is $56.35.
A quicker way
Use 10% and 1%: 10% of 49 is 4.9 and 1% is 0.49. 15% is 1 × 10% + 5 × 1% = 4.9 + 2.45 = 7.35.
Swap the numbers if that is easier: 15% of 49 is always the same as 49% of 15, because both are 15 × 49 ÷ 100.
Check the answer
Work backwards: 7.35 ÷ 49 × 100 = 15%. Getting 15% back shows the answer is right.
Rounding
Rounded to a whole number the result is 7, to one decimal place 7.3 and to two decimal places 7.35. 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: 4% of 11
- Turn the percentage into a decimal: 4 ÷ 100 = 0.04
- Multiply: 0.04 × 11 = 0.44
Common percentages of 49
10% of 49 is 4.9, 20% is 9.8, a quarter (25%) is 12.25, half (50%) is 24.5 and three quarters (75%) is 36.75. Knowing these makes it easy to estimate any other percentage of 49 in your head.
Adding and taking away 15%
Increasing 49 by 15% gives 56.35 and decreasing it by 15% gives 41.65. These do not cancel out: raising 49 by 15% and then lowering the result by 15% ends at 47.8975, because the second 15% is taken of a bigger number.
Finding the original number
If 7.35 is 15% of something, divide by 0.15 to get it back: 7.35 ÷ 0.15 = 49. This is how you work out a price before tax or a full amount from a share of it.
