Answer:
a) Leopard = 87%
31-4 = 27
= 87%
b) Cat = 87 %
it was obvious because they both from the cat family xD
c) Sheep = 90%
3 different in the sequence so by the same formula as above we get 90%
d) Goat = 90% too
e) Chimpanzee = 96.7 %
only one difference in the sequence
f) horse = 87%
4 different
we could group them into 100% thats going to be human,96.7 % mammal, 90%, 87%.
