FAQ

Everything you need to know about this question

Why do I divide by 100 to convert a percentage?

+

Because percent means "per hundred"! So 35% literally means 35 out of 100, or 35100=0.35 \frac{35}{100} = 0.35 .

Is there a shortcut for finding percentages of 100?

+

Yes! When finding a percentage of 100, the answer is simply the percentage number itself. So 35% of 100 = 35, 72% of 100 = 72, etc.

What if the percentage is greater than 100%?

+

The same method works! For example, 150% of 100 = 1.5×100=150 1.5 \times 100 = 150 . Your answer will be larger than the original number.

How can I check if my percentage calculation is reasonable?

+

Think logically: 50% should be half, 25% should be one-quarter, 10% should be one-tenth. Does your answer make sense compared to these benchmarks?

Do I always need to use decimals for percentage problems?

+

Not always! You can also use fractions: 35% of 100 = 35100×100=35 \frac{35}{100} \times 100 = 35 . Both methods give the same answer.
