10 1/2
10 9/10
-2.0
-2.7
10 1/5
11 1/10

-2.9

Answer 1

To find two numbers from the given list that sum to about 8, let's examine the options:

1. -1.1
2. 11 1/2 (which is 11.5)
3. 10 1/2 (which is 10.5)
4. 10 9/10 (which is 10.9)
5. -2.0
6. -2.7
7. 10 1/5 (which is 10.2)
8. 11 1/10 (which is 11.1)
9. -3.0
10. -4.0
11. 9 1/5 (which is 9.2)
12. -2.9

The only reasonable pairs to consider are the positive numbers. The closest options above 8 are 9 1/5 (9.2) and those below (but close to it).

• If we take -1.1 (negative number) and 9 1/5 (9.2), the sum would be approximately:

  -1.1 + 9.2 = 8.1 (which is close to 8)

Thus, the two numbers whose sum is about 8 are: -1.1 and 9 1/5 (9.2).
