$\dfrac{1}{6m}+\dfrac{2}{5m}+\dfrac{4}{m}$ The least common denominator of these fractions is $30m$. Adjust these fractions based on this LCD by multiplying each numerator by the same amount needed to multiply its corresponding denominator to turn it into the LCD: $\dfrac{1}{6m}+\dfrac{2}{5m}+\dfrac{4}{m}=\dfrac{5+12+120}{30m}=...$ Simplify: $...=\dfrac{137}{30m}$
