Question

If $x=\frac{-2}{7}$, then $|-x|$ is equal to ___________.

• A. $\frac{2}{7}$
• B. $\frac{-2}{7}$
• C. $0$
• D. $1$

Answer 1

The correct option is A $\frac{2}{7}$

Given, $x=-\frac{2}{7}$

Thus $-x=\frac{2}{7}$

$|-x|=|\frac{2}{7}|$

Mod converts the negative numbers to positive and no effect for positive number.

So, $|\frac{2}{7}|=\frac{2}{7}$
