Express the following in the form of $ \sf{\frac{p}{q}}$ :-

» 3.8

$\Large {\textsf{\textbf{\green{ツ ~~~Solution :-}}}}$

• To convert 3.8 in the form of $\sf{\frac{p}{q}}$, we will check the place value of decimal. And, to check the place value of decimal, we must check the digit after decimal.

$\tt{3. \underline{8}}$

• Hence, the underlined digit '8' shows that there is 1 digit after decimal. Hence, we will multiply the given number with 10.

$\mapsto \tt{3.8 \times 10}$

$\mapsto \tt{38}$

• Now, we will take 10 as the denominator of 38.

$\mapsto \tt{38}$

$\mapsto \frak \red{ \frac{38}{10} }$

• Hence, the form of 3.8 into $ \sf{\frac{p}{q}}$ will be $\bf \red{\frac{38}{10}}$.
