Question

Write a proportion that can be used to find the cost of 5 peaches if 3 peaches cost $1.20.

Answer 1

$1.20 divided by 3 is 0.40. So the cost is $0.40 per peach. 0.40 multiplied by 5 equals $2.00. The Answer is 5 peaches cost $2.00.

Answer 2

Assuming this is from Gradpoint, your options are:

A) 1.20 / 5  =  3 / X

B) 3 / 1.20  =  X / 5

C) 3 / 1.20  =  5 / X

D) 5 / 1.20  =  3 / X

Then analyzing the question ad turning words into numbers, to make things easier. Knowing instantly that 3 peaches equals $1.20, you have 3  =  1.20. Then glancing over at the 5, there's missing info. Therefore, you'd have 5  =  X.

So, judging from the options, your answer would be A)   1.20 / 5  =  3 / X.
