how many cakes is jahnay making?

recipe: makes 1 cake
150 g sugar
120 g butter
200 g flour

Jahnay makes 3 cakes bc 120g butter u times by 3 and gets u 360g and u get 3 cakes

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
