Question

What is 15.5% as a fraction of lowest terms?

Answer 1

`31/200`

Explanation:

`15.5%` Express `%` as "part of `100`" (divide by `100`)
`=15.5/100` Multiply the numerator and denominator by 10 to have a whole number on the top and bottom
`=(15.5*10)/(100*10)=155/1000` Since 155 and 1000 both end in 0 or 5, 5 is a factor of both, so divide them both by 5.
`=(155/5)/(1000/5)=31/200`
Since 31 is prime, this must be the simplest form.
