Question

How do you convert 3.12 into a fraction and percent?

Answer 1

As a percentage `312%`

As a fraction `78/25`

Explanation:

`3.13` is the same as `3+1/10+2/100`

This in tern is the same as `312/100`

But percentages use 100 as the denominator so `312/100-> 312%`

As a fraction in simplified form `(312-:4)/(100-:4)-> 78/25`
