Question
Subtract as indicated:
$\frac{18}{5}$ from $\frac{23}{3}$

Answer

The denominators of the given fractions are 3 and 5.
The LCM of 3 and 5 is 15.
Then, $\frac{23}{3}=\frac{23 \times 5}{3 \times 5}=\frac{115}{15}, \frac{18}{5}=\frac{18 \times 3}{5 \times 3}=\frac{54}{15}$
Therefore, $\frac{23}{3}-\frac{18}{5}=\frac{115}{15}-\frac{54}{15}=\frac{61}{15}=4 \frac{1}{15}$
