Step 1: Rewrite the Division as Multiplication by the Reciprocal
To divide by a fraction, multiply by its reciprocal. Rewrite the expression:
\[
\frac{18}{4} \div \frac{17}{2} = \frac{18}{4} \times \frac{2}{17}.
\]
Step 2: Simplify the Fractions
Simplify the fractions by canceling common factors. The numerator \( 18 \) and denominator \( 4 \) can be simplified by dividing both by \( 2 \):
\[
\frac{18}{4} = \frac{9}{2}.
\]
Now, the expression becomes:
\[
\frac{9}{2} \times \frac{2}{17}.
\]
Step 3: Multiply the Fractions
Multiply the numerators and denominators:
\[
\frac{9 \times 2}{2 \times 17} = \frac{18}{34}.
\]
Step 4: Simplify the Result
Simplify the fraction \( \frac{18}{34} \) by dividing both numerator and denominator by \( 2 \):
\[
\frac{18}{34} = \frac{9}{17}.
\]
