Question

73% of what is 156.4?

Answer 1

`x=214.25`

Explanation:

`73%` means `73/100`

Let `73%` of `x` be `156.4`

This means `73/100` of `x` is `156.4` and in equation form, we can write it as

`73/100 xx x=156.4=1564/10`

or `73/100 xx 100/73 xx x=1564/10xx100/73`

or `x=1564/10xx100/73`

As `73` is a prime number and `1564` is not a multiple of `73`,

we have to use a calculator and using it to calculate (up to 2dp)

`x=214.25`
