Very Easy.
1/3 is the same as 0.33333
3 and 1/2 is 3.5
So from greatest to least (3 and 1/2, 3, 1/3, 0.3, 0.03)
One car 40 miles /gallon
other car 30 miles/gallon
..
Total miles = 165
gas used = 45 gallons
...
let first car drive x miles
second car drive y miles
..
x/40 + y/30 = 45
(30x+40y)/30*40 = 45
30x+40y = 45*40*30
30x+40y=54,000
