Question

What is 20% of 46.60?

Answer 1

`9.32`

Explanation:

As a generic approach, a percentage is always a ratio. `x%` simply means `x/100`.

So, if you want to compute the `x%` of a certain number `n`, you only need to multiply `n` and `x/100`, obtaining

`(nx)/100`.

So, you may say that the `20%` of `46.60` is

`\frac{46.60*20}{100}`

However, some percentages are "easy", in the sense that they can be easily computed. For example, `50%` is a half, so instead of multiplying by `50/100`, you can simply divide by `2`.

By the same logic, you have `20/100 =1/5`, which means that the `20%` of something is one fifth of that something. So, it might be easier to compute

`46.60/5=9.32`
