Session 8, Part A:
Interpreting Fractions, Units, and Unitizing

In This Part: Interpretation of Fractions | Units and Unitizing

Math problems should either implicitly or explicitly define what unit you're working with. Without this context, some problems are ambiguous. In such cases, you should identify the units before doing any computation. Problems A2-A4 are examples of problems with ambiguous units.

Problem A2

Solution  

The shaded part could represent 5, or 2 1/2, or 5/8, or 1 1/4. Name the unit in each of these cases.


 

Problem A3

Solution  

Given that the six points are evenly spaced on the number line, what common fraction corresponds to Point E?


 

Problem A4

Solution  

a. 

The shaded part of the figure below is 3 2/3:

Specify the unit that is defined implicitly.

b. 

Using that same unit, how much would four small rectangles represent?

c. 

List three or more other values that the shaded part of the figure above could represent, and name the unit in each case.


 

Problem A5

Solution  

Three turkey slices together weigh 1/3 pound. Jake is allowed only four ounces of turkey for his lunch. How many turkey slices can he eat?


Stop!  Do the above problem before you proceed.  Use the tip text to help you solve the problem if you get stuck.
