Hint: We first try to describe the relation between the denominator and the numerator to find the simplified form. We use the G.C.D of the denominator and the numerator to divide both of them. We get the simplified form when the G.C.D is 1. We divide both sides of the equation $w=fd$ by $d$. That gives the value of $f$ in $w=fd$.

We need to solve for $f$ in $w=fd$. Here $w=fd$ has been expressed as the multiplication of $f$ and $d$. We divide both sides of the equation $w=fd$ with $d$.
So, $\dfrac{w}{d}=\dfrac{fd}{d}$. The right side of the equation becomes $\dfrac{fd}{d}=f$
For any fraction $\dfrac{p}{q}$, we first find the G.C.D of the denominator and the numerator. If it’s 1 then it’s already in its simplified form and if the G.C.D of the denominator and the numerator is any other number x then we need to divide the denominator and the numerator with x and get the simplified fraction form as $\dfrac{{}^{p}/{}_{x}}{{}^{q}/{}_{x}}$.
For our given fraction $\dfrac{fd}{d}$, the G.C.D of the denominator and the numerator is $d$.
Now we divide both the denominator and the numerator with $d$ and get $\dfrac{{}^{fd}/{}_{d}}{{}^{d}/{}_{d}}=\dfrac{f}{1}=f$.
Therefore, the solution for $f$ in $w=fd$ is $\dfrac{w}{d}$.
