To solve \( \frac{20}{3}-\frac{38}{9} \), we first need a common denominator. The denominators are 3 and 9, with 9 being the least common multiple. We convert \( \frac{20}{3} \) to have a denominator of 9: \[ \frac{20}{3} = \frac{20 \times 3}{3 \times 3} = \frac{60}{9} \] Now, we can subtract: \[ \frac{60}{9} - \frac{38}{9} = \frac{60 - 38}{9} = \frac{22}{9} \] So the final answer is \( \frac{22}{9} \).
