Question

Which is bigger: `0.45` or `2/5`?

Answer 1

`0.45 > 2/5`

Explanation:

Reducing both fracions to the same denominator and comparing the numerators

`0.45 = 45/100 = (9 xx 5)/(20 xx 5) = 9/20`

In the other fraction we have

`2/5 = (2 xx 4)/(5 xx 4) = 8/20`

so we conclude:

`0.45 > 2/5`
