CPM Homework Help : CC2MN Problem 9-107

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

A line segment, from 0% to 100%, divided into 10 equal segments, with label 1.0 above 100% on the right end. 2 brackets on top, 3 brackets on bottom, include sections and labeled as follows: Top, Left, first 3 sections, a. Top Right, last 4 sections, b. Bottom First, first 1.5 sections, d, bottom second, second 1.5 sections, d, third, last 4 sections, c.

Hint:

How many sections is this line divided into? Can you use this to find the value of each section?

Help:

Since the line is divided into $10$ sections, the sections each represent $10\%$ or $0.1$ of the whole.

More help:

To solve, note how many sections each bracket includes.

Answer:

$a=0.3$
$b$ - Use the method above to solve.
$c=40\%$
$d$ - Use the method above to solve.
Note that the two sections are equal.
