1a. 150games/3yrs = 50 games/yr won.
50-30 = 20games/yr lost.
20games/yr * 3yrs = 60 games lost.

1b. Ratio = 150Won/60Lost = 2.5/1.
Ratio = 50Won/20Lost = 2.5/1.

2. Rate = 180Mi/3h = 60 mi/1h.

3. 27Atoms/9Molecues=3 Atoms/1Molecue.

4. Tiffany: 46c./3 oz. = 15.33c./oz'
Tony: 76C./13 oz = 5.85 C./oz.
Tony got the best buy.

5. Larry: 10Prob./17Min=0.588 Prob./min.
Mary: 9Prob./16Min = 0.563 Prob/min.

6. Rate = 15 oz/3Qt = 5 oz/Qt.

7. Kim: 3Mi/21Min = 0.143 Mi/Min.
Ted: 4.5Mi/42Min = 0.107 Mi/Min.
Kim walked the fastest.

8. 7th Grade: (120-62)/120 = 29/60=0.483
8th Grade: 58/120 = 29/60 = 0.483.

9. 6/(6+8) = 6/14 = 3/7.
