The 36 fourth graders in Mrs. Thompson’s class had a year-end celebration. They decided to have a “Festival of Wheels.” For this celebration, each member of the class brought a method of transportation that they use that requires wheels. ½ of the class brought bicycles. 1/3 of the class brought skateboards, 1/12 of the class brought unicycles, and another 1/12 brought tricycles. How many wheels were involved in this “Festival of Wheels”? Explain how you would obtain the answer.
-
18 brought bicycles, which means 36 wheels.
12 brought skateboards, which means 24 wheels, I think.
3 brought unicycles, which means 3 wheels.
3 brought tricycles, which means 9 wheels.
36 + 24 + 3 + 9 = 72 wheels
12 brought skateboards, which means 24 wheels, I think.

36 + 24 + 3 + 9 = 72 wheels

1/2 * 36 = 18 bicycles with 36 wheels
1/3 * 36 = 12 skateboards (4 wheels each?)
1/12 * 36 = 3 unicycles = 3 wheels
1/12 * 36 = 3 tricycles with 9 wheels
so total is 36 + 3 + 9 + wheels on 12 skateboards
1/3 * 36 = 12 skateboards (4 wheels each?)
1/12 * 36 = 3 unicycles = 3 wheels
1/12 * 36 = 3 tricycles with 9 wheels
so total is 36 + 3 + 9 + wheels on 12 skateboards
