Question

chose 2 numbers whose sum is -18
4.5
-22 1/4
5.5
-23 1/2
-24 3/4
-22 1/2
6.75
4.25

Answer 1

To find two numbers from the list whose sum is -18, let's first convert any mixed numbers and fractions to improper fractions or decimals to make the calculations easier:

- \( -22 \frac{1}{4} = -22.25 \)
- \( -23 \frac{1}{2} = -23.5 \)
- \( -24 \frac{3}{4} = -24.75 \)
- \( -22 \frac{1}{2} = -22.5 \)

Now the list looks like this:
- 4.5
- -22.25
- 5.5
- -23.5
- -24.75
- -22.5
- 6.75
- 4.25

Now, let's check combinations to find a pair that sums to -18.

1. **-22.25 + 4.5 = -17.75** (too high)
2. **-22.25 + 5.5 = -16.75** (too high)
3. **-22.25 + 6.75 = -15.5** (too high)
4. **-22.25 + 4.25 = -18** (this works!)

The two numbers that sum to -18 are **-22.25 and 4.25**.
