$c. \$\\frac{18}{6}\$ — \$\\frac{17}{4}\$$

c. \$\frac{18}{6}\$ — \$\frac{17}{4}\$

Simplify $\frac{18}{6}$: $18\div6 = 3$, so $\frac{18}{6}=3$.
Simplify $\frac{17}{4}$: $17\div4 = 4.25$, so $\frac{17}{4}=4.25$.

Now we compare 3 and 4.25. Since $3<4.25$, we have $\frac{18}{6}<\frac{17}{4}$.

$\frac{18}{6}<\frac{17}{4}$
