Question

If we divide 9 by 2 on a number line, then the remainder will be _____.

• A.
  2
• B.
  1
• C.
  3
• D.
  0

Answer 1

The correct option is B

1

Division is repeated subtraction. Therefore, to divide 9 by 2 we have to subtract 2 repeatedly.
On a number line, subtracting 2 means taking backward jumps with each jump covering 2 units.
As shown on the number line we can have maximum 4 jumps and we will reach 1. We cannot jump backward further.

Therefore, when 9 is divided by 2 we will get 1 as remainder.
