Question: Legoland has 5 kangaroos for each koala. If Legoland has 180 kangaroos, how many koalas and kangaroos are there altogether?
Answer with step-by-step thinking: 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.
So the answer is 216.


Question: Keegan is in school for 7.5 hours each day and he is taking 7 classes. He has history and chemistry classes for a combined total of 1.5 hours. How many minutes does Keegan spend in one of his other classes on average?
Answer with step-by-step thinking: He has 7 - 2 = 5 other classes. 7.5 hours - 1.5 hours = 6 hours. 6 hours = 360 minutes. 360 / 5 = 72 minutes. Keegan spends 72 minutes in one of his other classes.
So the answer is 72.

Dorothy paid $12 for 3 gold coins so each gold coin is worth $12 / 3 = $4. The Tavern master originally had $20 worth of gold coins which is $20 / $4 = 5 gold coins. He gave 3 out of 5 gold coins to Dorothy so he now has 5 - 3 = 2 gold coins left.
So the answer is 2.
