Answer 2

The proportion is
`(y)/(x) =(1)/(25)`

Explanation:

We have to:

In June 20 of 500 wagons failed

On July 25 of 625 wagons failed

If we call x the number of wagons and and the number of wagons that had failures then we have to for June:

`(y)/(x) = (20)/(500)\\\\(y)/(x) = (1)/(25)`

For July we have

`(y)/(x) = (25)/(625)\\\\(y)/(x) = (1)/(25)`

The proportions are the same for both months

`(20)/(500) = (25)/(625)`

The proportion is
`(y)/(x) =(1)/(25)`

This means that of every 25 wagons, one has faults
