1. 37/15+49/15= 86/15
2. 97/12-86/15= 432/18= 2.35

Answer 3

7 + 13/12 - (2 + 7/15 + 3 + 4/15)

First, let's simplify the expression inside the parentheses:

2 + 7/15 + 3 + 4/15 = 5 + 11/15

Now, we can substitute this back into the original expression:

7 + 13/12 - (5 + 11/15) = 7 + 13/12 - 5 - 11/15 = 7 - 5 + 13/12 - 11/15 = 2 + 13/12 - 11/15

To subtract the fractions, we need to find a common denominator. The least common multiple of 12 and 15 is 60.

Converting 13/12 and 11/15 to have a common denominator of 60:

13/12 * 5/5 = 65/60 11/15 * 4/4 = 44/60

Now we can subtract the fractions:

2 + 65/60 - 44/60 = 2 + (65 - 44)/60 = 2 + 21/60 = 2 + 7/20

So, the final answer is 2 + 7/20.
