5-9.

Find the missing values on the diagram below. Assume that each line is evenly divided.

 $\qquad \;a \qquad \qquad \qquad \qquad \qquad \qquad \qquad \qquad \quad \;\;\, 144\\ \; \overbrace{\qquad \qquad \quad \;} \quad \qquad \qquad \qquad \qquad \quad \; \overbrace{\qquad \qquad \qquad \qquad \qquad \;\,}$ $0\% \;\, \underbrace{\qquad \;\;} \qquad \qquad \qquad \qquad \qquad \quad \quad \;\;\;\, \underbrace{\qquad \qquad \qquad \qquad \qquad \;\, } \; 100\%\\ \quad \quad \; 10\% \qquad \qquad \qquad \qquad \qquad \qquad \qquad \qquad \qquad \;\; c \\ \quad \;\;\, \underbrace{\qquad \qquad \qquad \qquad \qquad \qquad \quad }\\ \qquad \qquad \qquad \quad \;\;\;\, b$

If the line is evenly divided, then each interval represents $10\%$ of the total value.
How many intervals are contained within $b$?

There are 5 intervals which means that $b$ represents $50\%$.

Follow the same method for $c$.

$144$ represents $40\%$ of the total value. So how much does $20\%$ represent?
