Chicken and rabbit in the same cage, a total of 100 heads, 320 feet, then, chicken has______ There are two rabbits______ Only
(320-100 × 2) △ 4-2, = (320-200) △ 2, = 120 △ 2, = 60, 100-60 = 40. Answer: there are 40 chickens and 60 rabbits. So the answer is: 40, 60
There are 36 heads from the top and 100 feet from the bottom. How many are there in each cage?
Suppose all rabbits, chicken: (4 × 36-100) / (4-2) = 44 / 2 = 22; rabbit: 36-22 = 14; answer: there are 22 chickens and 14 rabbits
Chickens and rabbits in the same cage, 12 heads and 32 feet, ask: how many chickens and rabbits each?
