Explanation:

Step1: Analyze each year's gas price

• 2007: $3.02\ 4/10$ (which is $3.02 + \frac{4}{10}=3.02 + 0.4 = 3.42$)
• 2003: $1.45\ 2/10$ (which is $1.45+\frac{2}{10}=1.45 + 0.2 = 1.65$)
• 2001: $1.54\ 8/10$ (which is $1.54+\frac{8}{10}=1.54 + 0.8 = 2.34$)
• 2009: $2.59\ 7/10$ (which is $2.59+\frac{7}{10}=2.59 + 0.7 = 3.29$)

Step2: Compare the prices

Compare the decimal values: $3.42$ (2007), $1.65$ (2003), $2.34$ (2001), $3.29$ (2009). We can see that $3.42$ is the largest.
