Work Step by Step

First, let us complete the multiplication in the numerator and the denominator to get a standard ratio that we can simplify: $$\frac{7\cdot6}{4\cdot3}=\frac{42}{12}$$To simplify a ratio, we divide by a fraction that is equal to $1$ (a fraction with the same number in the numerator and denominator is equal to $1$). In this case, we use $\frac{6}{6}$: $$\frac{42}{12}\div\frac{6}{6}=\frac{7}{2}$$
