40kg=m
Swap sides so that all variable terms are on the left hand side.
\frac{40kg}{40k}=\frac{m}{40k}
Divide both sides by 40k.
g=\frac{m}{40k}
Dividing by 40k undoes the multiplication by 40k.
40kg=m
Swap sides so that all variable terms are on the left hand side.
40gk=m
The equation is in standard form.
\frac{40gk}{40g}=\frac{m}{40g}
Divide both sides by 40g.
k=\frac{m}{40g}
Dividing by 40g undoes the multiplication by 40g.
