Plastic cups comes in an 10-pack, but paper plates come in a 12 pack. What is the smallest number of plastic cups and paper plates you can purchase if you want to have the same number of each for an upcoming BBQ?

The answer is 60. You can find this out by finding the least common multiple of 10 and 12, which is 60 because 10x6=60 and 12x5=60. Hope this helps :)
