In Algebra, you will need to be able to work with numbers, words, and geometric representations. Use these representations to answer the following problems.  

1. Draw and shade a figure that represents $100\%$. Label $100\%$ below it. Then describe the figure in words. 

   Answer (a):

   Diagrams will vary.

   The figure can be described as a whole.

   

2. Similarly, draw and shade figures that represent $50\%$, $25\%$, and $150\%$. Label each figure and describe it in words.

   Answer (b):

   Diagrams will vary. The shaded areas are the answers.

   

3. Draw and shade a figure that represents “one-third.” How can this figure be represented with a number?

   Answer (c):

   

   $\frac{1}{3}$

4. Describe what the diagram at right represents using words and numbers.
