Answer 1

Answer:

(1) 10.1

Step-by-step explanation:

Given :

To find the equivalent value of $(\frac{0.4}{0.04} + \frac{0.04}{0.4} )$,.

Solution :

We know that,

0.4 = 4 times $\frac{1}{10}$ = $\frac{4}{10}$

&

0.04 = 4 times $\frac{1}{100}$ = $\frac{4}{100}$

∴ $\frac{0.4}{0.04}$ = $\frac{4}{10}$ ÷ $\frac{4}{100}$

= $\frac{4}{10}$ × $\frac{100}{4}$ = 10

   

∴ $\frac{0.04}{0.4}$ = $\frac{4}{100}$ ÷ $\frac{4}{10}$

= $\frac{4}{100}$ × $\frac{10}{4}$ = $\frac{1}{10}$

∴ $(\frac{0.4}{0.04} + \frac{0.04}{0.4} )$ = $10 + \frac{1}{10} = \frac{10X10 + 1}{10} = \frac{101}{10} = 10.1$
