Answer 3

Let's solve the given equations one by one:

1. $-4.65 - 7.35 + 9$

Using the rules of arithmetic:

$-4.65 - 7.35 + 9 = -12 + 9 = -3$

2. $21 - 16.8 - 13.2$

Using the rules of arithmetic:

$21 - 16.8 - 13.2 = 21 - 30 = -9$

3. $-34.7 + 70 - 35.3$

Using the rules of arithmetic:

$-34.7 + 70 - 35.3 = 70 - 34.7 - 35.3 = 70 - 70 = 0$

4. $-18 - 5.44 + 2.56$

Using the rules of arithmetic:

$-18 - 5.44 + 2.56 = -18 - 2.88 = -20.88$

So, the results are:

1. -3
2. -9
3. 0
4. -20.88
