So far she has edited 114 pages

Step-by-step explanation:

If she edited 38% of 300 pages, the number of pages she edited can be found by simply multiplying the decimal form of 38% (38% = 0.38) times the total number of pages of the book:

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:

2
