Answer from: Quest

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

\frac{2}{5}=\frac{x-18}{x}

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

\frac{2}{5}=\frac{30-18}{30}

\frac{2}{5}=\frac{12}{30}
