4-1/2
You asked:
Evaluate the expression: \(4 - \frac{1}{2}\)
MathBot Answer:
\[ 4 - \frac{1}{2} = \frac{7}{2} = 3.5 \]
The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{4}{1}\) and \(\frac{-1}{2}\) is \(2\). \[ \begin{aligned} 4 - \frac{1}{2} &= \frac{4 \cdot 2}{1 \cdot 2} + \frac{-1 \cdot 1}{2 \cdot 1} \\ &= \frac{8 + -1}{2} \\ &= \frac{7}{2} \end{aligned} \]
