Dividend, divisor, Quotient, Remainder

Dividend = divisor x Quotient + Remainder


72 = 1 x 72 + 0

72 = 2 x 36 + 0

72 = 3 x 24 + 0

72 = 4 x 18 + 0

72 = 5 x 14 + 2

72 = 6 x 12 + 0

72 = 7 x 10 + 2

72 = 8 x 9 + 0

72 = 9 x 8 + 0

72 = 11 x 6 + 6


Interpret these:

24/6

24 marbles are shared among 6 friends

30/3 = 10

30 marbles, 3 friends, each gets 10

96/24 = 4

96 marbles, 24 friends, each gets 4

5 x 6 = 30

5 friends, each has 6 marbles, total 30 marbles

24/5

24 marbles, 5 friends, each gets 4, 4 are left

15 = 2 x 7 + 1

15 marbles, 2 friends, each gets 7, 1 is left

Nine threes are twenty-seven.

9 friends, each has 3 marbles, total 27 marbles

4 + 5 = 9

2 friends (A and B), A has 4 marbles, B has 5 marbles, total 9 marbles

6 + 7 + 8 = 21

3 friends (A, B and C), A has 6 marbles, B has 7 and C has 8, total 21 marbles

10 – 4 = 6

A has 10 marbles, he gives B four, 6 are left with A


You have 9 friends. You want to give them chocolates (equally). How many chocolates should you buy?

9, 18, 27, 36, 45 … [multiples of 9]

You have 14 friends. You want to give them chocolates (equally). How many chocolates should you buy?

14, 28, 42, 56, 70, 84, 98, 112, 126, 140 …


100/25 = ?

25, 50, 75, 100, 125 …

Quotient: 4

Because 100 is the 4th multiple of 25.

92/23 = ?

23, 46, 69, 92, 115 …

Quotient: 4

Because 92 is the 4th multiple of 23.

98/19 = ?

19, 38, 57, 76, 95, 114 …

Quotient: 5 [remainder: 3]

123/27 = ?

27, 54, 81, 108, 135 …

Quotient: 4 [remainder: 15]

INTERPRETATION OF DIVISION Is it possible to give 72 marbles to 1 person? Yes 72 is exactly divisible by 1. 1 divides 72 exactly. 1 is a factor of 72. The person gets 72 marbles. Nothing remains. i.e., REMAINDER=0 72/1=72 It means, 72 marbles can be given to 72 people and each will get 1. 72 is also a factor of 72. 72/72=1, REMAINDER=0 1 and 72 are factors of 72. [72/1=72 and 72/72=1; this is true for every number; 45/1=45 and 45/45=1; 104/1=104 and 104/104=1; therefore, 1 is a factor of every number; every number is a factor of itself.] Is it possible to share 72 marbles between 2 friends equally? Yes 72 is exactly divisible by 2. (36 times) 2 divides 72 exactly. (36 times) 2 is a factor of 72. 72/2=36, remainder=0 72 is DIVIDEND, 2 is DIVISOR, 36 is QUOTIENT. (72 is numerator, 2 is denominator) The other situation is, 72/36=2, remainder=0 72 marbles, shared equally among 36 people, each will get 2 marbles. 36 is a factor of 72. 2 and 36 are factors of 72.
