Question

Find the sum or difference.

$\frac{3}{7}+\left(-\frac{2}{7}\right)$

Short answer

$\frac{1}{7}$

Step-by-step solution

Step 1. Given Information.

The provided expression is $\frac{3}{7}+\left(-\frac{2}{7}\right)$.

Step 2. Calculation.

Since, the denominators of the first and second fractions of the expression $\frac{3}{7}+\left(-\frac{2}{7}\right)$ are the same, subtract the numerators of both fractions to calculate the difference.

$\begin{array}{c}\frac{3}{7}+\left(-\frac{2}{7}\right)=\frac{3-2}{7}\left[\text{writedifferenceofnumeratorsoverdenominator}\right]\\ \frac{3}{7}+\left(-\frac{2}{7}\right)=\frac{1}{7}\left[\text{subtract}\right]\end{array}$

Step 3. Conclusion.

The difference is $\frac{1}{7}$.
