Answer 1

a)21
b)12
c) Quotient=7 , Remainder=1

Answer 2

Step-by-step explanation:

Repeated subtraction is related to division as the number of times the number is subtracted is called the quotient and left over is called the remainder.

a) 84÷4

84-4=80

80-4=76

76-4=72

72-4=68

68-4=64

64-4=60

60-4=56

56-4=52

52-4=48

48-4=44

44-4=40

40-4=36

36-4=32

32-4=28

28-4=24

24-4=20

20-4=16

16-4=12

12-4=8

8-4=4

4-4=0

4 is used 21 times and so the quotient is 21 and remainder is 0.

b) 36÷3

36-3=33

33-3=30

30-3=27

27-3=24

24-3=21

21-3=18

18-3=15

15-3=12

12-3=9

9-3=6

6-3=3

3-3=0

3 is used 12 times and so the quotient is 12 and remainder is 0.

c) 57÷8

57-8=49

49-8=41

41-8=33

33-8=25

25-8=17

17-8=9

9-8=1

8 is used 7 times to get the number 1 and so the quotient is 7 and remainder is 1.
