11. What is “cancelling”, really? Use cancelling to solve the following: 6000/20 = 152/8 = 345/5 =

12. Using our description of cancelling above solve: (20 + x)/20 =

13. What is “cancelling”, really? Revise our description: 152/8 == (160 – 8)/8 = 345/5 = = (340 + 5)/5 =

14. And a connection 22 ÷ 7 = 3 R 1 means 22 = 7  3 + 1 How are these related?

15. 5 ÷ 3 = 1 R 2 means 5 = 3  1 + 2 20 ÷ 12 = 1 R8 means 20 = 12  1 + 8

16. Explain why 5 ÷ 3 = (5 4) ÷ (3 4) without doing any calculations
