Exercise 2.
Answer each question using what you have learned about the relationship of division and subtraction.
a. If 12 ÷ x = 3 how many times would x have to be subtracted from 12 in order for the answer to be zero? What is the value of x?
Answer:
3; x = 4
b. 36 − f − f − f − f = 0. Write a division sentence for this repeated subtraction sentence. What is the value
of x?
Answer:
36 ÷ 4 = f or 36 ÷ f = 4; f = 9

Question 1.
Represent 56 ÷ 8 = 7 using subtraction. Explain your reasoning.
Answer:
56 – 7 – 7 – 7 – 7 – 7 – 7 – 7 – 7 = 0 because
56 – 7 = 49; 49 – 7 = 42; 42 – 7 = 35; 35 – 7 = 28; 28 – 7 = 21; 21 – 7 = 14; 14 – 7 = 7; 7 – 7 = 0.
OR
56 – 8 – 8 – 8 – 8 – 8 – 8 – 8 = 0 because
56 – 8 = 48; 48 – 8 = 40; 40 – 8 = 32; 32 – 8 = 24; 24 – 8 = 16; 16 – 8 = 8; 8 – 8 = 0.
Question 2.
Explain why 30 ÷ x = 6 is the same as 30 – x – x – x – x – x – x = 0. What is the value of x in this example?
Answer:
30 ÷ 5 = 6, so x = 5. When I subtract 5 from 30 six times, the result is zero. Division is a repeat operation of
subtraction.
