im not quite sure if this is right but i got 5.6 oisutuve

step-by-step explanation:

the answer is 62

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.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

8 2/3 is the answer
