I believe the ratio of maraianne's height to jean-lucs height would be,
(2 - 6) (1 - 2) An then x the variable. - NOT THE ANSWER
x Is gonna be 2 x 6 x 6 x 3.14 and then x at the end.so it's..... 226.08 then I move the decimal making it 2.26.
x = 2.26
There useful because all sorts of things are measured in fractions and you need ratios for all sorts of things like for income and stuff
I don't know if this is the true answer, but I would say 3.73
