Let the required number be x.

Then we need to find x such that x% of 80 is 14.

Now we will rewrite into an equation.

==> x% * 80 = 14

`==gt x/100 * 80 = 14`

Simplify buy dividing by 20.

`==gt x/5 * 4 = 14 `

`==gt (4x)/5 = 14`

Now we will multiply by reciprocal.

`==gt x = 14*5/4 `

`==gt x = 35/2 = 17.5`

==> Then 17.5 % of 80 is 14.

?% of 80 is 14

`(14)/(80) = 0.175`

multiply 0

0.175 by 100 to get the percentage

`.175xx100=17.5`

14 is 17.5% of 80
