CPM Homework Help : ACC6 Problem 5-9

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

A line segment, from 0% to 100%, with ten equal sections. A bracket includes the first section, labeled 10 %. A bracket includes the first 2 sections, labeled a. A bracket includes the first 5 sections, labeled b. A bracket includes the last 4 sections, labeled 144 and c.

Hint:

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

Answer:

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

Hint 2:

Follow the same method for $c$ .

More Help:

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