Question

What is 3/4 as a decimal?

Answer 1

`3/4=0.75`

Explanation:

For converting a fraction into decimal, we should first reduce the fraction to its lowest terms. As `3/4` is already in lowest term, we can skip it here.

Further as factors of denominator `4` are only 2s, we should have terminating decimals (for terminating decimals, we should have only 2 and 5 as prime factors of denominator). In fact there are two 2s, hence to convert it into decimal we can multiply numerator and denominator by two 5s i.e. `5xx5`

Now dividing `3` by `4`, we get

`3/4=(3xx5xx5)/(4xx5xx5)=75/100=0.75`
