Answer 2

To solve these arithmetic expressions, we'll perform the calculations step by step:

1. -9.5 - 3 7/20:

First, let's convert the mixed number 3 7/20 to a decimal. To do that, we divide 7 by 20:

7 ÷ 20 = 0.35

Now we can subtract:

-9.5 - 0.35 = -9.85

Therefore, the result is -9.85.

2. 6.7 - (-4 8/25):

Again, let's convert the mixed number -4 8/25 to a decimal. We divide 8 by 25:

8 ÷ 25 = 0.32

Now we have:

6.7 - (-0.32)

Remember that subtracting a negative is the same as adding a positive. So, we can rewrite the expression as:

6.7 + 0.32 = 7.02

Therefore, the result is 7.02.
