Probing questions
37 × 64 = 2368. Explain how you can use this fact to devise calculations with answers 23.68, 2.368, 0.2368.
2368 ÷ 64 = 37. Explain how you can use this fact to devise calculations with answers 3.7, 3700, 0.37?
3.2 × 23 = 73.6. Explain how you can use this fact to devise other calculations with the same answer.
73.6 ÷ 3.2 = 23. Explain how you can use this fact to devise other calculations with the same answer.
