\frac{7}{4}L=m
Calculate 7 to the power of 1 and get 7.
\frac{\frac{7}{4}L}{\frac{7}{4}}=\frac{m}{\frac{7}{4}}
Divide both sides of the equation by \frac{7}{4}, which is the same as multiplying both sides by the reciprocal of the fraction.
L=\frac{m}{\frac{7}{4}}
Dividing by \frac{7}{4} undoes the multiplication by \frac{7}{4}.
L=\frac{4m}{7}
Divide m by \frac{7}{4} by multiplying m by the reciprocal of \frac{7}{4}.
\frac{7}{4}L=m
Calculate 7 to the power of 1 and get 7.
m=\frac{7}{4}L
Swap sides so that all variable terms are on the left hand side.
