B.

Step-by-step explanation:

Given fraction :

Here, numerator

denominator=

Therefore, the prime factorization form of the given fraction to get the simplest from is

The simplest form of the fraction

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:
