The Guinness book of world records states that the tallest trophy is about 270 inches. If they stacked 4 of those trophies on top of each other, how high would they be? answer plz

Hey there!

If the tallest trophy is about 270 inches, and you stack 4 of those trophies on top of each other, you'd be multiplying 270 times 4.

270×4= 1,080

So, if you stacked four 270-inch trophies on top of each other, they would be 1,080 inches high.

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:

what is the original number? you forgot to add it.
