c.) =

#### Work Step by Step

a.) $\frac{2}{3}$ ? 0.67
The $\frac{2}{3}$ roughly equates to .$\overline{6}$ (The overline means that it keeps going on forever), so the 0.67 is $\frac{2}{3}$roughly rounded to the hundredth.
$\frac{2}{3}$ = 0.67
b.) $\frac{2}{3}$ ? -0.67
Natural numbers are always bigger than negative integers
$\frac{2}{3}$ $\gt$ -0.67
c.) $\mid$0.67$\mid$ ? $\mid$-0.67$\mid$
The Second Property of the Absolute value states $\mid$a$\mid$ = $\mid$-a$\mid$. This correlates that any number (despite being positive or negative) will always be positive.
$\mid$0.67$\mid$ = $\mid$-0.67$\mid$
