Frieda Friendly works for a local car dealership. She noticed that $\frac { 3 } { 4 }$ of the cars are sedans and that half of them are white. What fraction of the dealership’s cars are white sedans?  

1. Use a unit rectangle to represent this situation. Label the parts carefully.

   Step 1 (a):

   Draw a rectangle. A rectangle is drawn to the left.

   Step 2 (a):

   Subdivide the rectangle and label appropriately. The rectangle is divided into 2 rows and 4 columns of 8 equal parts

   Hint (a):

   One dimension will represent the dealership's different types of cars, while the other will represent the dealership's different colors of cars.

   Step 3 (a):

   Shade half of them to represent the white cars, and three-fourths to represent the sedans. The area of the overlapping region is the answer. Shading added as follows: 3 left columns of top row, blue, last column of top row, orange, 3 left columns of bottom row, purple.

   

   

   

2. Write an equation or a sentence that describes the situation, and answer the question.

   Hint (b):

   Write an equation that finds the area of the overlapping region. Then you can find the answer.
   See problem 2-89 for examples.

   Answer (b):

   $\frac{3}{4}\cdot\frac{1}{2}=\frac{3}{8}$

3. Write your answer from part (b) as a decimal and as a percent.

   Hint (c):

   Convert the fraction into a decimal by dividing the numerator by the denominator. Convert the decimal into a percent by multiplying it by $100\%$ or moving the decimal.
