Answer Key

1. C. It may be easier to compare these numbers by converting the fractions to decimals by dividing the numerator by the denominator, or by converting all the fractions to the form with the lowest common denominator.

2. D. It may be easier to compare these numbers by converting the fractions to decimals by dividing the numerator by the denominator, or by converting the fractions to the form with the lowest common denominator.

3. B. Since there are two of all these fractional parts, and answer B has the biggest denominator, it is the smallest in terms of unit size, and so the smallest number.

4. C. Dividing each number by 100 and multiplying by the amount of the percent.

5. A. You can determine each value by dividing the percentage by 100 and then multiplying by the total amount (i.e., 80 for answer A).

6. C. You can solve this problem by setting up the equation = x/1000.

7. A. You can solve this problem by setting up the equation 3/5 = x/10,000

8. A. One way to solve this problem is to substitute values in the first equation, and then note how the right side of the second equation can be altered to maintain its truth.

9. B. The only unit of measure for volume among the responses is cubic inches.

10. D. Divide 12 by 20 and multiply by 100.
