Question

An Olympic-size swimming pool holds 2,500 kiloliters of water. After swimmers splash water out of the pool, there are 24,500 hectoliters of water left in the pool. How many hectoliters of water did the swimmers splash out of the pool?

Answer 1

There are 25,000 hectoliters in 2,500 kiloliters. So, subtract 25,000-24,500 and you have your answer, which is 500 hectoliters. :)
