Section 1.6 Division of Whole Numbers 55 5 1 16 0 27. 28. 29. 80 30. 13 13 31. Show that 6 3 2 but 3 6 2 by using multiplication to check. 32. Show that division is not associative, using the numbers 36, 12, and 3. Concept 3: Long Division 33. Explain the process for checking a division problem when there is no remainder. 34. Show how checking by multiplication can help us remember that 0 5 0 and that 5 0 is undefined. For Exercises 35–46, divide and check by multiplying.
