# Worksheet on Number in Expanded Form

Practice the questions given in the worksheet on number in expanded form. Expanded form of a number is to break down each digit and write the number to show how each digit in the number represents different values.

We can learn expanded form of a number in the following ways:

(i) if we write the number in words.

(ii) if we arrange the digits in a place value.

1. Name the hundreds, tens and ones for each number in both ways:

For example:

145 = 1 hundreds + 4 tens + 5 ones

= 100 + 40 + 5

(i) 256

(ii) 327

(iii) 473

(iv) 789

(v) 847

2. Four ways of showing hundreds, tens and ones. Complete the table with the help of the first row.

For example:

 The abacus Columns Expanded form Standard form
 H1 T3 O1 100 + 30 + 1 131 H..... T..... O..... ................ ........ H..... T..... O..... ................ ........ H..... T..... O..... ................ ........ H..... T..... O..... ................ ........ H..... T..... O..... ................ ........

3. Write the number in standard form:

(i) 200 + 30 + 1

(ii) 900 + 10 + 7

(iii) 500 + 40 + 9

(iv) 800 + 20 + 6

(v) 400 + 70 + 3

(vi) 700 + 30 + 3

(vii) 300 + 0 + 4

(viii) 200 + 30 + 0

4. Write in expanded form:

(i) 365

(ii) 248

(iii) 827

(iv) 980

(v) 405

(vi) 319

Answers for worksheet on number in expanded form are given below to check the above questions.

1. (i) 256 = 2 hundreds + 5 tens + 6 ones

= 200 + 50 + 6

(ii) 327 = 3 hundreds + 2 tens + 7 ones

= 300 + 20 + 7

(iii) 473 = 4 hundreds + 7 tens + 3 ones

= 400 + 70 + 3

(iv) 789 = 7 hundreds + 8 tens + 9 ones

= 700 + 80 + 9

(v) 847 = 8 hundreds + 4 tens + 7 ones

= 800 + 40 + 7
