Question

54 is what percent of 80?

Answer 1

Explanation:

You write this as follows:

`(54)/(80) = (x)/(100\%)`

I suggest you cross multiply. This is where the product of the numerator of the left side and the denominator of the right side equals the product of the numerator of the right side and the denominator of the left side.

`54 * 100\% = x * 80`

Once you write it out, you just need to isolate the x. Right now the x is multiplied by 80. You need to do the inverse operation to get x alone. This means you divide both sides by 80 to get:

`(54 * 100\%)/(80) = x`

Therefore x=67.5%
