FAQ

Everything you need to know about this question

Why do I multiply by 100 to get a percentage?

+

Because percent means "per hundred"! When you multiply by 100, you're finding how many parts out of 100 your fraction represents. So 827 \frac{8}{27} becomes about 29.62 parts out of 100.

How many decimal places should I round to?

+

For percentages, two decimal places is usually standard (like 29.62%). However, always check what your teacher or the problem asks for - some want whole numbers only!

Can I convert to a decimal first, then multiply by 100?

+

Absolutely! Both methods work: 827=0.2962... \frac{8}{27} = 0.2962... , then 0.2962 × 100 = 29.62%. Choose whichever feels easier to you!

What if I get a repeating decimal like 29.629629...?

+

That's normal! 827 \frac{8}{27} creates a repeating decimal. Just round to the precision asked for - usually 2 decimal places for percentages.

How do I know if 29.62% or 29.63% is more accurate?

+

Look at the third decimal place! Since 80027=29.629... \frac{800}{27} = 29.629... , the third digit is 2, which is less than 5, so we round down to 29.62%.
