Question

Write a division problem that has a 3-digit dividend and a divisor between 10 and 20. Show how to solve it by drawing a quick picture.

Answer 1

1230 ÷ 10 = 123
you can draw it by placing a decimal point after the 0 in 1230, and when you divide by 10, the decimal point goes after the 3.

Answer 2

In the division problem,

The number which is divided is called dividend,

While, the number which divides, is called divisor,

Let dividend = 150 ( a three digit number ),

Divisor = 15 ( a number between 10 and 12 ),

So, the problem would be,

`150/ 15`

In the below figure,

Take a grid that shows 150,

Divide this grid such that each box represents 15,

Thus, there are such 10 boxes,

That is,

`150/ 15 = 10`
