If $A=\frac{1}{4}$ and $B=-\frac{1}{2}$, what is the absolute value of the difference between $18A$ and $18B$? Express your answer as a decimal to the nearest tenth.
\(If \;\;A=\frac{1}{4} \;\;and \;\;B=-\frac{1}{2}\)
what is the absolute value of the difference between $18A$ and $18B$? Express your answer as a decimal to the nearest tenth.
18|1/4--1/2| = 18*3/4 = (9*3)/2 = 13.5
