Solution
Subtract and simplify the expression \( \frac{4z - 9}{3z} - \frac{3z - 8}{4z} \).
Find a common denominator.
The common denominator for \( 3z \) and \( 4z \) is \( 12z \).
Rewrite each fraction with the common denominator.
The first fraction becomes \( \frac{4z - 9}{3z} = \frac{4z - 9}{3z} \cdot \frac{4}{4} = \frac{16z - 36}{12z} \) and the second fraction becomes \( \frac{3z - 8}{4z} = \frac{3z - 8}{4z} \cdot \frac{3}{3} = \frac{9z - 24}{12z} \).
