Division of Decimals

655221

The process of long division is similar to that of dividing whole

numbers with some modifications.

Example: 2.556 1.2

Step 1. Move the decimal point in the divisor tothe right until it becomes a whole

number. (click)

Example: 2.556 1.2

655221 Step 1. Move the decimal point in the divisor tothe right until it becomes a whole

number.

Step 2. Move the decimal point in the dividend

to the right by the same amount. (click)

Jagdeep had a strip of paper measuring

1.8 m. He cut it into 4 equal strips. How

long is each shorter strip of paper?

I can show this using long

division.

Each strip of paper is 0.45 m long.

Zhiwei wants to divide 19 litres of water

equally into 6 pots. Find the volume of water

in each pot, correct to 2 decimal places.

Divide to 3 decimal places, then

round off the answer to 2 decimal

places.

3.166.. 3.17

There are about 3.17 litres

of water in each pot.
