This is how I'd set it up:
405/20 = 243/x 
this means the mpg (miles / gallons) for 1 situation is the same as the mpg for the other situation (because the rate is the same)
then just cross multiply and solve:
405x=243*20 or 405x=4860 or x = 12
he would need 12 gallons of gas for 243 miles

How to subtract unlike fractions
topjm [15]
Find the common denominator for both unlike fractions.

EX:   1                        2
         12                      8

The lowest common factor is both fractions is 24.           Multiply both denominators to get 24. 

Do not forget to multiply the numerators with the number you used to multiply the denominators together.        

You do not have to multiply each side by the same number.
