Sara was cleaning her room. She found 17 tiny toy cars and decided to give them to her 2 brothers. 

Sara divided the 17 tiny cars evenly between the 2 boys. Which equation shows how things worked out?

17 / 2 = 8 R1

17 / 2 = $8.50

17 / 2 = 8 1/2

Explain your choice. Why did you choose that equation?

17 / 2 = 8R1

 I chose this equation because there could be one car left over, the problem isn't talking about money and you can't cut a car in half.
