The image asks to solve for $c$ in terms of $a$ and $b$. The equation shown appears to be:

$\frac{b}{a} = \frac{c}{a}$

To solve for $c$ in terms of $a$ and $b$, we can cross-multiply to eliminate the denominators:

$b \cdot a = c \cdot a$

Now, divide both sides by $a$:

$c = b$

Thus, the solution is:

$c = b$

Tip: When solving equations with fractions, cross-multiplication is often a quick method to eliminate denominators and simplify the equation.
