Question

Represent $-\frac{9}{5}$ on a number line.

• A.
• B.

Answer 1

The correct option is B

Given fraction is $-\frac{9}{5}$
Here, denominator is a factor of $10.$

To convert $-\frac{9}{5}$ into a decimal number, convert the denominator into a power of $10.$

We know, $5\times 2=10$

$\therefore$ Multiply the numerator and denominator by $2$ to convert the denominator to $10.$

$-\frac{9\times 2}{5\times 2}$
$=-\frac{18}{10}$
(shift the decimal point to the appropriate place to make the denominator as $1$)
$=-\frac{1.8}{1}$
$=-1.8$

The number line representation is as follows:
