There are chickens and rabbits in a yard. Altogether there are 18 heads and 50 legs. How many rabbits are there?
Show hints
- Imagine all 18 animals have 2 legs each.
- Divide the difference 50 − 18 × 2 by 2.
Show the answer and solution
Answer: 7
If all were chickens, there would be 18 × 2 = 36 legs. The extra 50 − 36 = 14 legs come from rabbits, with 2 extra legs each. There are 14 ÷ 2 = 7 rabbits.
