Answer 2

Let's break down the expression step by step:

1. Start with the subtraction inside the parentheses: 3 - 1 5/12 = 2 7/12

2. Perform the division inside the parentheses: 2 7/12 ÷ 7/16 = (31/12) ÷ (7/16)

3. Invert the divisor and multiply: (31/12) * (16/7) = (31/12) * (16/7) = (31 * 16) / (12 * 7) = (496) / (84)

4. Simplify the fraction: 496/84 = 124/21

5. Now, add 5/14 to the result: 124/21 + 5/14

To add these fractions, you need to find a common denominator. In this case, the least common multiple of 21 and 14 is 42. So, we'll convert both fractions to have a denominator of 42:

(124/21) * (2/2) = 248/42 (5/14) * (3/3) = 15/42

Now, you can add the fractions:

(248/42) + (15/42) = (248 + 15) / 42 = 263/42

So, the final result is 263/42, which can be simplified further:

263/42 = 131/21

Therefore, the answer to the expression is 131/21.
