C=number of acres of corn
w=number of acres of wheat
total is 180 acres
c+w=180
wants to plant 3 times as many corn as wheat
c=3w
subsitute 3w for c in other
c+w=180
3w+w=180
4w=180
divide boh sides by 4
w=45
sub back
c=3w
c=3(45)
c=135
135 acres of corn and 45 acres of wheat
200 divided by 300000 = 0.000666666666667
