Question

The numerator of a certain fraction is 4 less than the denominator. If the fraction is equal to 2/3, what is the denominator of this fraction?

Answer 1

For this case we can create the following equation:

`(x-4)/(x)=(2)/(3)`

And solving for x we got:

`3(x-4)=2x`
`3x-12=2x`
`x=12`

Then the denominator is:

x=12
