Answer

$\frac{38}{21}$

Work Step by Step

We first turn the two whole numbers into fraction form, giving us the following: $\frac{19}{6} \div \frac{7}{4}$ We never can divide by a fraction. Rather, we must multiply the first fraction by the reciprocal of the second fraction. Because the reciprocal of 7/4 is 4/7, we obtain: $\frac{19}{6}\times \frac{4}{7} = \frac{76}{42}=\frac{38}{21}$.
