evaluate 3/7 + 9/28
You asked:
Evaluate the expression: \(\frac{3}{7} + \frac{9}{28}\)
MathBot Answer:
\[ \frac{3}{7} + \frac{9}{28} = \frac{3}{4} = 0.75 \]
The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{7}\) and \(\frac{9}{28}\) is \(28\). \[ \begin{aligned} \frac{3}{7} + \frac{9}{28} &= \frac{3 \cdot 4}{7 \cdot 4} + \frac{9 \cdot 1}{28 \cdot 1} \\ &= \frac{12 + 9}{28} \\ &= \frac{21}{28} \\&= \frac{3}{4} \end{aligned} \]
