Explain simply why 216 is the correct answer to: Legoland has 5 kangaroos for each koala. If Legoland has 180 kangaroos, how many koalas and kangaroos are there altogether?. Explanation:
For every 5 kangaroos, there is one koala, meaning for the 180 kangaroos, there are 180 / 5 = 36 koalas. Altogether, there are 36 + 180 = 216 koalas and kangaroos.
