Express in the form of decimals:
(a) $ \frac{13}{4} $
(b) $ -\frac{25}{40} $

Given :

The given rational numbers are

(a) $\frac{13}{4}$

(b) $\frac{-25}{40}$

To do :

We have to express the given rational numbers as decimals.

Solution :

(a) $\frac{13}{4}$ can be written as,

$\frac{13}{4}= \frac{13 \times 25}{4 \times 25}$

$= \frac{325}{100}$

$= 0.325$

Therefore, $\frac{13}{4}$ can be expressed as 0.325.

(b) $\frac{-25}{40}$ can be written as,

$\frac{-25}{40}= \frac{-25 \times 25}{40 \times 25}$

$= \frac{-625}{1000}$

$= -0.625$

Therefore, $\frac{-25}{40}$ can be expressed as $-0.625$.
