Question

a skateboard company is putting together boards and wheels to make skateboards. the company has a box of 36 boards. they need 4 times as many wheels as boards.wheels come in a pack of 20. how many packs of wheels should the company order ?

Answer 1

If you multiply 36 by four since there are 4 wheels for skateboard
you will get 144.  That number is the total number of wheels you need to order and since they come in packs of 20 what you need to do is divide 144 by 20 and you will get 7.2.  So obviously you can't order 7.20 packs of wheels so this means that 8 packs of wheels must be bought in order to ensure that all of the skateboards get wheels on them.
The answer is 8.
