Answer 1

Answer:

1. 135

2. 114

3. .19

4. 170

5. 336

6. 106.25

7. No, the associative property does not work for subtraction or division, they do not hold for the associative property. For example,

2+ (3+4) = (2+3) + 4       2- (3-4) = (2-3) – 4

2+7 = 5+4                      2 + 1 = -1-4

9 = 9                              3 = -5, which is not true

8. No, the commutative property does not work for subtraction or division, they will give a different result. For example,

5+6 = 6+5        5-6 ≠ 6-5
