In this problem, you have to formulate or illustrate the ratio of proportion:
$234 : 36 hours = $288 : 40 hours
To check if the rates are proportional, you have to multiply the inner numbers and the outer numbers. If the product is equal, then they are proportional
234 x 40 ? 288 x 26
9,360 ? 7,488
9,360 is not equal to 7,488
Therefore, the pay rates of these two people are not proportional.
