HBSE 7th Class Maths Solutions Chapter 2 Fractions and Decimals InText Questions 9
Using this table you can write a decimal number in its expanded form also. For example 253.417
= 2 x 100 + 5 x 10 + 3 x 1 + 4 x (\(\frac{1}{10}\)) + 1 x (\(\frac{1}{100}\)) + 7 x (\(\frac{1}{1000}\)). So, a decimaln number and its expanded form can be written if the place values of the digits are known to us.
