Cups are sold 5 to a package and plates are sold 10 to a package. If you want to have the same number of each item for the party, what is the least number of packages of each you need to buy?

Respuesta :

i think the answer would be 
20, the LCM 
(least common multiple) :)

1 package of plates = 10 plates  and 2 package of cups = 10 cups

 so 3 packages is least amount
