Harry is making bouquets of balloons. He makes the bouquets so that 2 out of every 5 balloons are red. Which equation correctly compares the number of balloons he uses, x, to the number of red balloons, y?
A. y = 2 3 x
B. y = 2 5 x
C. y = 3 2 x
D. y = 5 2 x

Two variables are said to be proportional if an increase or decrease in one variable leads to a corresponding change in the other variable by a value.

Let x represent the number of balloons he uses and let y represent the number of red balloons.

Since he makes the bouquets so that 2 out of every 5 balloons are red, hence the equation relating x to y is:

y = (2/5)x
