QUESTION 3
Easy
Simplify the expression:
\((−\frac{1}{4})\) + \((\frac{5}{12})\).
SOLUTION
The given expression is \((−\frac{1}{4}) + (\frac{5}{12})\)
The LCM of 4 and 12 = 12
\(\begin{aligned} (−\frac{1}{4}) + \frac{5}{12} &= \frac{−1(3) + 5}{12} \\ &= \frac{−3 + 5}{12} \\ &= \frac{2}{12} \\ &= \frac{1}{6} \end{aligned}\)
The LCM of 4 and 12 = 12
\(\begin{aligned} (−\frac{1}{4}) + \frac{5}{12} &= \frac{−1(3) + 5}{12} \\ &= \frac{−3 + 5}{12} \\ &= \frac{2}{12} \\ &= \frac{1}{6} \end{aligned}\)
