Question

How do you write `3/20` as a decimal?

Answer 1

`3/20 = 15/100 = 0.15`

Explanation:

Decimals are way of writing fractions which have denominators that are powers of `10`

`0.3 = 3/10" "0.38 = 38/100" "0.384 = 384/1000` etc

Find an equivalent fraction for `3/20`

`3/20 xx5/5 = 15/100`

This can now be written as `0.15`

For other fractions with denominators that are not factors of `10,100, 1000, etc`, you divide the numerator by the denominator:

`2/7 = 2 div 7 =0.2857...`

`5/9 = 5 div 9 = 05555...`
