Answer 2

Let's solve each of the given expressions:

1. 4.6 + (-3.8) To add these numbers, we add the corresponding components: 4.6 + (-3.8) = 4.6 - 3.8 = 0.8

2. -4.2 + (-5.8) Similarly, we add the corresponding components: -4.2 + (-5.8) = -4.2 - 5.8 = -10

3. 2.5 + (-3.5) Adding the corresponding components gives us: 2.5 + (-3.5) = 2.5 - 3.5 = -1

4. 4.7 + (-4.7) Adding the corresponding components, we get: 4.7 + (-4.7) = 4.7 - 4.7 = 0

Therefore, the results are:

1. 4.6 + (-3.8) = 0.8
2. -4.2 + (-5.8) = -10
3. 2.5 + (-3.5) = -1
4. 4.7 + (-4.7) = 0
