4/10 +2/20
You asked:
Evaluate the expression: \(\frac{4}{10} + \frac{2}{20}\)
MathBot Answer:
\[ \frac{4}{10} + \frac{2}{20} = \frac{1}{2} = 0.5 \]
The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{4}{10}\) and \(\frac{2}{20}\) is \(20\). \[ \begin{aligned} \frac{4}{10} + \frac{2}{20} &= \frac{4 \cdot 2}{10 \cdot 2} + \frac{2 \cdot 1}{20 \cdot 1} \\ &= \frac{8 + 2}{20} \\ &= \frac{10}{20} \\&= \frac{1}{2} \end{aligned} \]
