The name of place values are according to Indian system or according to the International system of numeration.

Number can be written in three different ways. 1) Standard form (numeral form) 2) Word form 3) expanded form.

5 ----> 500

6 ----> 60

8 ----> 8

So expanded form of 568 is

_________________________________________________________________

1 ----> 1000

2 ----> 200

4 ----> 40

5 ----> 5 So expanded form of 1245 is

_________________________________________________________________

0 ----> 00 (ten's place)

5 ----> 5 (one's place)

So the expanded form of 805 is

_________________________________________________________________

The easiest way to write the given number in standard form is :

1) Write the place value at the top according to the given number. 2) write the given number accordingly.

3) Cancel the number of zeroes and write the number in the same order of the place value.

Here, we have only three numbers, so at the top write

600 30 8

6

So the standard form of number is

_________________________________________________________________

Here, we have four numbers, so at the top write

1000 400 80 2

1

So the standard form of number is

**Practice**

1) Write the following numbers in expanded form.

- 345
- 541
- 1,236
- 2,354
- 409

2) Write in standard form.

- 2000 + 500 + 40 + 1
- 900 + 80 + 5
- 100 + 8
- 600 + 20 + 6
