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 … ...

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.
