Let’s solve each expression step by step, following the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

1. 27 / 3 + 8 × 7
   = 9 + 56
   = 65

2. 64 / 8 + 9 × 6
   = 8 + 54
   = 62

3. 3 × (75 - 45)
   = 3 × 30
   = 90

4. 2 × (12 + 18)
   = 2 × 30
   = 60

5. 42 / 6 × 4
   = 7 × 4
   = 28

6. 32 / 4 × 5
   = 8 × 5
   = 40

7. 0 × 1 / 2
   = 0 / 2
   = 0

8. 1 × 6 / 6
   = 6 / 6
   = 1

Here are the final answers:

1. 65
2. 62
3. 90
4. 60
5. 28
6. 40
7. 0
8. 1
