Answer 2

Let's solve the expressions step by step:

1. 9 + (-1 1/2)

To add these two numbers, first convert -1 1/2 into an improper fraction: -1 1/2 = -3/2

Now, add the fractions: 9 + (-3/2) = 9 - 3/2

To combine the whole number and the fraction, find a common denominator, which is 2: (9 * 2) - 3 = 18 - 3 = 15

So, the result is 15.

2. 8 + (-2 5/7)

Convert -2 5/7 into an improper fraction: -2 5/7 = -19/7

Now, add the fractions: 8 + (-19/7) = 8 - 19/7

To combine the whole number and the fraction, find a common denominator, which is 7: (8 * 7) - 19 = 56 - 19 = 37

So, the result is 37.

3. 5 + (-6 2/3)

Convert -6 2/3 into an improper fraction: -6 2/3 = -20/3

Now, add the fractions: 5 + (-20/3) = 5 - 20/3

To combine the whole number and the fraction, find a common denominator, which is 3: (5 * 3) - 20 = 15 - 20 = -5

So, the result is -5.
