Question

The area of a blackboard is 1 1 third square yards. A poster's area is 8 over 9 square yards. What is the unit rate of the blackboard's area to the poster's area?

Answer 1

Explanation:

Given that,

The area of a blackboard is
`1(1)/(3)=(4)/(3)\ \text{yards}^2`

The area of poster is
`(8)/(9)\ \text{yards}^2`

We need to find the unit rate of the blackboard's area to the poster's area. So, it can be calcualted by dividing blackboard's area to the poster's area.

So,

`((4)/(3))/((8)/(9))=(4)/(3)* (9)/(8)\\\\=1.5`

So, the rate of
`1.5\ \text{yard}^2`.
