Question

What is the solution to the proportion `32/40 = x/15`?

Answer 1

The answer is `x=12` .

Solve `32/40=x/15` .

Reduce `32/40` to `4/5` by dividing the numerator and denominator by `8`.

`4/5=x/15`

Cross multiply.

`5*x=4*15` =

`5x=60`

Divide both sides by `5`.

`cancel5/cancel5x=60/5` =

`x=12`
