1. C: The figure shows 2 completely shaded circles, plus 1/8 more than 4/8 shaded on the third circle. Thus, the figure represents the mixed number, 2 5/8.

2. B: The circle shows 1/8 more than 4/8, which represents 5/8.

3. C: The fraction, 12/18, is not equivalent to the fraction, 3/4, since the fractions do not represent the same ratio. The denominator for Choice C would need to be 16, for the two fractions to be equivalent.

4. B: The sum equals 0.90, which may also be written as 9/10.

5. C: The ten thousandths place is located 4 places to the right of the decimal.

6. C: The square of the given fraction may be written as 252/92 , or 625/81, which equals 7 58/81.

7. C: The sum of 3/8 cup of sugar and 3/5 cup of sugar is 39/40 cup of sugar. 39/40 cup of sugar can be compared to 15/16 cup of sugar by finding a common denominator. Doing so shows that Sarah will need 78/80 cup of sugar, but only has 75/80 cup of sugar. Thus, she needs 3/80 cup of sugar.

8. D: The following proportion may be used to find the solution: 8/0.5=x/7.75. Solving for x gives x = 124. Thus, there are 124 ounces in 7 3/4 pounds.

9. E: The value does not change because the 3 in the numerator and the 3 in the denominator cancel. 3XZ/3Y=XZ/Y.

10. B: 0.5% = 0.005, which may be written as 5/1000, which reduces to 1/200.

11. C: The number, 7, is a factor of 21, since 7 will divide evenly into 21.

12. B: The fraction of the daily consumption may be represented as 12.8/64, or 0.2. This decimal represents 1/5. Thus, a consumption of 12.8 ounces of water is 1/5 of the daily average consumption.

13. D: The amount you need to add is equal to the difference of 4/5 and 1/3. Finding a common denominator allows you to write 12/15-5/15, which equals 7/15. Thus, you need to add 7/15 cup of water.

14. A: The difference may be written as 3/4-2/4, which equals 1/4.

15. C: The difference may be written as 7 4/8-5 3/8, which equals 2 1/8.
