Answer 2

Let's solve each of these equations step by step:

1. (5 * 12 * 70) / 14 = 2100 / 14 = 150

2. (7 * 32 * 45) / 15 = 10080 / 15 = 672

3. (5 * 21 * 54) / 9 = 5670 / 9 = 630

4. 42c / 6 = 7c

5. (42 / 6) * c = 7c

6. 7c = 7c

7. 72xy / 12 = 6xy

8. (72 / 12) * xy = 6xy

9. 6xy = 6xy

10. 51ab / 3 = 17ab

11. (51 / 3) * ab = 17ab

12. 17ab = 17ab

13. 45xy / 15 = 3xy

14. (45 / 15) * xy = 3xy

15. 3xy = 3xy

16. 28xy / 7 = 4xy

17. (28 / 7) * xy = 4xy

18. 4xy = 4xy

So, each of these equations simplifies to the same expression on both sides, showing that they are all true.
