Step-by-step explanation:

The unit rate refers to how many area units of the poster are in the blackboard.

To find this rate, we just have to divide the area of the blackboard by the area of the poster.

Where represents the area of the blackboard in square yards.

Where represents the area of the poster.

Now, the ratio is

This mean that the unit rate is 1.5, that is, there are 6 square yards of blackboard per 2 square yards per poster.

the answer is 5/3x+7/5y+7
