suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. when carrying 10 gallons of fuel, the
airplane weighs 2055 pounds. when carrying 42 gallons of fuel, it weighs 2231 pounds. how much does the airplane weigh if it is carrying 60 gallons of fuel?

This is also called the LCM or the Least Common Multiple! To find it you have to factor out both numbers:

      8=2*2*2
    10=2       *5   and I made space on purpose because there are no 5's in #8
LCM=2*2*2*5=40 seconds
Looking down from 8 to 10 you see that under first number 2 there is another 2, but under second, and third number 2 there is no other 2's. The first one is going to be written only once even though there are two of them and I even put it in bold so you would notice what I'm talking about.

Hope this helps and if you have any questions let me know!
