How many chickens are there? ** There are 60*(2/3)=<<60*(2/3)=40>>40 chickens.
How many cows are there? ** There are 60-40=<<60-40=20>>20 cows.
How many legs do the chickens have? ** The chickens have 40*2=<<40*2=80>>80 legs.
How many legs do the cows have? ** The cows have 20*4=<<20*4=80>>80 legs.
How many legs do the animals have altogether? ** They have 80+80=<<80+80=160>>160 legs altogether.
