Answer
Answer :
a) 7.2
b) 0
c) $\frac{1}{2}$
Work Step by Step
$\rightarrow$To find absolute value, just remove the sign in front of the number.
$\rightarrow$If the number is negative, make it positive.
$\rightarrow$If the number is positive, then let it remain as it is, just remove the positive(+) sign ( if any).
$\rightarrow$ DO NOT change the number, remove only the sign.
$\rightarrow$ eg. |-7.2| = 7.2
|0|=0
|-$\frac{1}{2}$| = $\frac{1}{2}$
