Answer 1

The cost of 1 CD is $15. 3/8 multiplied by 1/4 is 3/32. 3/5 divided by 1/3 is 9/5.

Step-by-step explanation:

To find the cost of 1 CD, you need to divide the total cost of the CDs by the number of CDs purchased. In this case, 4 CDs were purchased for $60, so the cost of 1 CD is $60 divided by 4, which is $15. Therefore, the correct answer is b) $15.

To multiply fractions, you multiply the numerators together and the denominators together. 3/8 multiplied by 1/4 is (3 * 1)/(8 * 4), which simplifies to 3/32. Therefore, the correct answer is a) 3/32.

To divide fractions, you multiply the first fraction by the reciprocal of the second fraction. 3/5 divided by 1/3 is the same as 3/5 multiplied by 3/1, which is (3 * 3)/(5 * 1), or 9/5. Therefore, the correct answer is a) 9/5.
