Chapters 5, 6 and 7
Remember to show all steps and check your work carefully.

Problem Remember to simplify all answers

1. A restaurant has 7 booths and 16 tables. Write the ratio of tables to booths as a fraction.
16 tables divided by 7 booths
= 16/7

2. Write the ratio of to 6 in simplest form.
(4 1/3) / (6)
= (13/3) / (18/3)
= 13/18

3. Find the rate:
392 feet/ 8 seconds
= 49 feet per second

4. Determine whether the pair of fractions is proportional:
Yes. 6/15 is equal to 2/5 (divide the top and bottom of the fraction both by 3)

5. Use percent notation to name the shaded portion of the drawing.

72 shaded squares/100 total
= 72/100
= 0.72
= 72%

6. Rewrite the statement, using percent notation.
