Question

Write the following decimal numbers in the expanded form. 

(i) 30.04 

(ii) 3.04 

(iii) 300.04

Answer 1

(i) 30.04 = 3 x 10 + 0 x 1 + 0 x \(\frac{1}{10}\) + 4 x \(\frac{1}{100}\) 

= 3 x 10 + \(\frac{4}{100}\)

(ii) 3.04 = 3 x 1 + 0 x \(\frac{1}{10}\) + 4 x \(\frac{1}{100}\) 

= 3 x 1 + \(\frac{4}{100}\)

(iii) 300.04 = 3 x 100 + 0 x 10 + 0 x 1 + 0 x \(\frac{1}{10}\) + 4 x \(\frac{1}{100}\) 

= 3 x 100 + \(\frac{4}{100}\) 

= 3 x 100 + \(\frac{4}{100}\)
