Jen uses 8.6 gallons of gasoline to drive 164.7 miles. Which is the best estimate for the number of miles per gallon of gasoline her vehicle gets?

19.15 miles/gallon

Step-by-step explanation:

Gasoline used = 8.6 gallons

Distance driven = 164.7 miles

Number of miles per gallon = Distance driven / Gasoline used

= 164.7 miles / 8.6 gallons

= 19.151162790697 miles/gallon

Approximately 19.15 miles/gallon

Number of miles per gallon of gasoline her vehicle gets is 19.15 miles/gallon

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
