Question 149
Here is a table which gives the information about the total rainfall for several months compared to the average monthly rains of a town. Write each decimal in the form of rational number $\frac{p}{q}$.
$\begin{array}{cc}\text{Months}& \text{Above/Below normal (in cm)}\\ \text{May}& 2.6924\\ \text{June}& 0.6096\\ \text{July}& -6.9088\\ \text{August}& -8.636\end{array}$

Answer 1

$i)May=2.6924=\frac{26924}{10000}$ [remove decimal]

$\Rightarrow \frac{p}{q}=\frac{6731}{2500}cm$ [after dividing numerator and denominator by 4]

$ii)June=0.6096=\frac{6096}{10000}$ [remove decimal]

$\Rightarrow \frac{p}{q}=\frac{381}{625}cm$ [after dividing numerator and denominator by 16]

$iii)July=-6.9088$

$=-\frac{69088}{10000}$ [remove decimal]

$\Rightarrow \frac{p}{q}=-\frac{4318}{625}cm$ [after dividing numerator and denominator by 16]

$iv)August=-8.636=-\frac{8636}{1000}$ [remove decimal]

$\Rightarrow \frac{p}{q}=-\frac{2159}{250}cm$ [after dividing numerator and denominator by 4]
