Question

Which number should be added to 3651 to make it divisible by 21?

Answer 1

3651 /21

So remainder is 18

18 will add to 3651.

Answer 2

Answer:

3 must be added to dividend 3651 to make it divisible by 21

Step-by-step explanation:

Given :3651

To Find: Which number should be added to 3651 to make it divisible by 21

Dividend =( Divisor*Quotient)+Remainder

3651 = (21*173)+18

Since after dividing 3651 by 21 we get remainder = 18

Hence the remainder is 18 which is (21-18=3) less than divisor 21

So, 3 must be added to dividend 3651

3651+3=3654

Dividend =( Divisor*Quotient)+Remainder

3654=(21*174)+0

Hence no remainder so, 3654 is completely divisible by 21

So, 3 must be added to dividend 3651 to make it divisible by 21
