\frac{2+4}{7}+\frac{1}{7}=\frac{3}{7}
Since \frac{2}{7} and \frac{4}{7} have the same denominator, add them by adding their numerators.
\frac{6}{7}+\frac{1}{7}=\frac{3}{7}
Add 2 and 4 to get 6.
\frac{6+1}{7}=\frac{3}{7}
Since \frac{6}{7} and \frac{1}{7} have the same denominator, add them by adding their numerators.
\frac{7}{7}=\frac{3}{7}
Add 6 and 1 to get 7.
\text{false}
Compare \frac{7}{7} and \frac{3}{7}.
