\frac{3}{m}\times \frac{2m}{3}
Since \frac{1}{m} and \frac{2}{m} have the same denominator, add them by adding their numerators. Add 1 and 2 to get 3.
\frac{3\times 2m}{m\times 3}
Multiply \frac{3}{m} times \frac{2m}{3} by multiplying numerator times numerator and denominator times denominator.
2
Cancel out 3m in both numerator and denominator.
