cars : SUV's = 4:1 = 16:4
SUV's : Minivans = 4:5
now that I have a common "4" for the SUV's in both, I can say
cars : SUV's : minivans = 16 : 4 : 5
or
= 16x : 4x : 5x
but 5x = 20
x = 4
so we have 64 cars, 16 SUV's , and 20 minivans for a total of 100 vehicles
check:
cars: SUV's = 64:16 = 4 : 1
SUV's : minivans = 16 : 20 = 4 : 5
