There are 50 chickens and 160 feet in the same cage. If all chickens are assumed to be rabbits, then 50 rabbits will have (?) feet, which will be more than the actual (?): Why are there so many more chickens? Because if a chicken is assumed to be a rabbit, it will have (?) feet, which will be more than the actual (?) = (?), we need to divide (?) by (?) = (?) if a chicken is assumed to be a rabbit, then rabbits will have (?) - (?) = (?)
200 feet, 40 feet more than the actual, because the rabbit has four feet, while the chicken has only two feet
40 divided by 2 = 20 chickens and 50-20 = 30 rabbits
