A cookie recipe calls for 113 cups of walnuts. Jen wants to use only half of this amount. How many cups of walnuts should Jen use? A. 2/3
B. 8/6
C. 1/3
D. 8/3

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:

yeah i know the problem you need. i am taking it right now. the answer is step 3
