In expanded form of a number, the number is shown according to the place values of its digits.
This is shown here:
In 2385, the place values of the digits are given below:
Hence, 2385 = 2000 + 300 + 80 + 5
Thus, 2000 + 300 + 80 + 5 is the expanded form of 2385.
For example:
1. Find the expanded form of 453169.
Solution:
Place values of digits 453169
So, 453169 = 400000 + 50000 + 3000 + 100 + 60 + 9
2. Write the number in figures and then in words for the following expanded form:
(i) 80000 + 8000 + 500 + 50 + 7
Solution:
80000 + 8000 + 500 + 50 + 7
= 88557 (in figures)
Eighty eight thousand five hundred fifty seven (in words)
(ii) 100000 + 30000 + 2000 + 10 + 6
Solution:
100000 + 30000 + 2000 + 10 + 6 = 132016 (in figures)
One hundred thirty two thousand sixteen (in words)
We can write the expanded form of numbers in different ways.
3. Write in expanded form:
(i) 28369
Write as:
(a) 20000 + 8000 + 300 + 60 + 9
(b) 2 × 10000 + 8 × 1000 + 3 × 100 + 6 × 10 + 9 × 1
(c) 2 ten thousands + 8 thousands + 3 hundreds + 6 tens + 9 ones
(ii) 419,247
Write as:
(a) 400000 + 10000 + 9000 + 200 + 40 + 7
(b) 4 × 100000 + 1 × 10000 + 9 × 1000 + 2 × 100 + 4 × 10 + 7 × 1
(c) 4 hundred thousands + 1 ten thousands + 9 thousands + 2 hundreds + 4 tens + 7 ones
