Food problem solving
We can use chicken legs and rabbit legs to express quantity and relationship, and turn the problem into a food problem, which is more intuitive and easy to understand.
magnitude relation
First, we multiply 107 by 4, and the result is twice the total number of rabbit legs and chicken legs. Then, we know that rabbit legs are 56 more than chicken legs, so if we subtract 56 from the total, there are three times as many chicken legs left.
Quantitative calculation
The number of drumsticks is (107 * 4-56)/3, that is, 124! Next, the number of chickens is half of the number of drumsticks, that is, 124/2=62.
Quantitative calculation
Finally, the number of rabbits is the total number 107 MINUS the number of chickens 62, which is 45.
Open mind
Through this method to solve the food problem, we can understand the problem more intuitively and make our thinking more open.
