Question

What is `23/25` in decimal form?

Answer 1

`23/25=0.92`

Explanation:

To convert a fraction into decimal, one needs to first make the denominator a power of `10`. It is easy if denominator's only prime factors are `2` and `5`. As one can multiply by `5`s and `2`'s to get the same.

Here in `23/25`, we have `25=5xx5` so do we need to multiply by `2xx2`.

Hence `23/25=(23xx2xx2)/(25xx2xx2)`

= `92/100=0.92`
