Answer:

4. 4/5

5. 2 1/4

7. 5/8

12. 1 1/5

Explanation:

  • All of your answers are correct except for 4., 5., 7., and 12.

4.

8/10 can be simplified by dividing both the numerator and denominator by 2 (i.e., the greatest common factor between 8 and 10):

(8 / 2) / (10 / 2)

4/5

Thus, the final answer is 4/5.

5.

  • You correctly converted 3 to 12/4 to have two denominators that are the same.

However, 12/4 - 3/4 = 9/4.

  • When you convert 9/4 to a mixed number, the quotient is 2, the remainder is 1, and the divisor 4.
  • Because a mixed number is essentially quotient + remainder/divisor, the answer as a mixed number is 2 1/4.

7.

  • You correctly converted 3/4 to 6/8 to have two denominators that are the same.

However, 6/8 - 1/8 = 5/8.

12.

Your product was wrong which affected your answer when trying to convert the product to a mixed number (however, you correctly converted 30/16 to a mixed number, which is commendable):

4/5 * 6/4

(4 * 6) / (5 * 4)

24/20

The greatest common factor of 24/20 is 4, so we divide both numbers by 4:

(24 / 4) / (20 / 4)

6/5

  • When you convert 6/5 to a mixed number, the quotient is 1, the remainder is 1, and the divisor is 5.

Thus, the answer as a mixed number is 1 1/5.

4. 8/10 can be simplified to 4/5.
5. 12/4 - 3/4 = 9/4 = 2 1/4.
7. 6/8 - 1/8 = 5/8
11. Circle your final answer (7/15).
12. 4 • 6 = 24. 5 • 4 = 20. 24/20 = 1 1/5.

The rest look great!
