Consider the question. Annie is a mother of 3 children: Mark, Matt, and Mike. She decided to give them some fruits. Mike received 3 oranges. Matt got twice as many apples, and Mark got as many bananas as Mike and Matt received fruits altogether. How many fruits do the three children have in total?
 If the answer is '18'; explain the reasoning:
Mike received 3 oranges. Matt received twice as many apples as Mike received oranges, so he got 3 * 2 = 6 apples. Mark received 6 + 3 = 9 bananas. So in total, all children received 3 + 6 + 9 = 18 fruits.
