Step-by-step explanation:

Question 3:

2/7 + 1/4=> 8/28 + 7/28=> 15/28

Hence, Option D is the correct answer.

Question 4:

Since you have like fractions in the mixed fractions, you can simply add them.

=> 3 1/5 + 2 3/5=> 5 4/5

Hence, Option A is the correct answer

Question 5:

=> 5 2/5 + 4 1/3=> 27/5 + 13/3=> 81/15 + 65/15=> 146/15=> 9 11/15

Hence, Option C is the correct answer

Question 6:

=> 7/8 - 3/8=> 4/8 = 1/2

Hence, Option C is the correct answer.

Question 7:

=> 4/5 - 2/3=> 12/15 - 10/15=> 2/15

Hence, Option A is the correct answer.

Question 8:

=> Since you have like fractions in the mixed fractions, you can simply subtract them.

=> 3 2/7 - 1 3/7=> 1 6/7

Hence, Option C is the correct answer.

Question 9:

=> Since you have like fractions in the mixed fractions, you can simply subtract them.
