Answer 2

1. To add 3 1/5 and 2/5, we need to find a common denominator. The common denominator here is 5.

Converting the mixed number 3 1/5 to an improper fraction: 3 1/5 = (3 * 5 + 1)/5 = 16/5

Adding the fractions: 16/5 + 2/5 = (16 + 2)/5 = 18/5

Therefore, 3 1/5 + 2/5 = 18/5.

2. To add 3 2/11 and 1 5/11, we need to find a common denominator. The common denominator here is 11.

Converting the mixed numbers to improper fractions: 3 2/11 = (3 * 11 + 2)/11 = 35/11 1 5/11 = (1 * 11 + 5)/11 = 16/11

Adding the fractions: 35/11 + 16/11 = (35 + 16)/11 = 51/11

Therefore, 3 2/11 + 1 5/11 = 51/11.

3. To subtract 3 3/7 and 2/7, we need to find a common denominator. The common denominator here is 7.

Converting the mixed number 3 3/7 to an improper fraction: 3 3/7 = (3 * 7 + 3)/7 = 24/7

Subtracting the fractions: 24/7 - 2/7 = (24 - 2)/7 = 22/7

Therefore, 3 3/7 - 2/7 = 22/7.

4. To subtract 9 11/15 and 3 7/15, we need to find a common denominator. The common denominator here is 15.

Converting the mixed numbers to improper fractions: 9 11/15 = (9 * 15 + 11)/15 = 146/15 3 7/15 = (3 * 15 + 7)/15 = 52/15

Subtracting the fractions: 146/15 - 52/15 = (146 - 52)/15 = 94/15

Therefore, 9 11/15 - 3 7/15 = 94/15.

5. To subtract 4 9/11 and 3 10/11, we need to find a common denominator. The common denominator here is 11.

Converting the mixed numbers to improper fractions: 4 9/11 = (4 * 11 + 9)/11 = 53/11 3 10/11 = (3 * 11 + 10)/11 = 43/11

Subtracting the fractions: 53/11 - 43/11 = (53 - 43)/11 = 10/11

Therefore, 4 9/11 - 3 10/11 = 10/11.

I hope this helps! Let me know if you have any other questions.
