Question

Five out of 10 marbles in a bag are red. What percentage of the marbles are not red?

Answer 1

50%

Explanation:

Five out of 10 is 50%

Answer 2

50%

Explanation:

If there are 5 out of 10 marbles that are red, then there are
`10-5 =5` marbles that aren't red.

This makes the fraction
`(5)/(10)`. Converting a fraction to a percent is simple - divide the numerator by the denominator and multiply by 100.

`5 / 10 = 0.5\\\\0.5 \cdot 100 = 50`

So 50% of the marbles aren't red.

Hope this helped!
