Answer 1

90/x = 70/100

Explanation:

Answer 2

Greetings!

We can create an equation that can be used to solve problems of this kind:

`90= ((70)/(100))x`
Let x represent the number.

Solve for x.

`90= (70)/(100)x`

Divide both sides by
`(70)/(100)`

`(90)/((70)/(100))= ((70)/(100)x)/((70)/(100))`


`((90)/(1))({(100)/(70)})=x`


`(9000)/(70)=x`

Reduce the fraction to lowest terms or a decimal

`(900)/(7)=x`

The Answer Is:

`\left[\begin{array}{ccc} x=(900)/(7)\end{array}\right]`

70% of
`(900)/(7)` is equal to 90.

Hope this helps!
