Unit rate of the blackboard's area compared to the poster's area = $\frac{8}{33}$

Unit rate of the poster's area compared to the blackboard's area = $\frac{33}{8}$

A detailed explanation:

Rates are useful for assessing or contrasting two distinct quantities.

The unit rate enables us to relate how quantity 1's units correspond to quantity 2's units.

We have the following information:

Area of Blackboard = $\frac{11}{3}$

Area of Poster = $\frac{8}{9}$

Unit rate of the blackboard's area versus the poster's area: This indicates how one unit area of the blackboard correlates to the area of the poster.

$= \frac{\text{Area of Poster}}{\text{Area of Blackboard}}$ $= \frac{\frac{8}{9} }{\frac{11}{3} }$

= $\frac{8}{33}$

Therefore, one unit area of the blackboard corresponds to $\frac{8}{33}\text{ area of poster}$

Unit rate of the poster's area in relation to the blackboard's area: This represents how one unit area of the poster relates to the blackboard's area.

$= \frac{\text{Area of Blackboard}}{\text{Area of Poster}}$ $= \frac{\frac{11}{3} }{\frac{8}{9} }$

= $\frac{33}{8}$

Consequently, one unit area of the poster corresponds to $\frac{33}{8}\text{ area of blackboard}$
