Question

Lola is placing appetizers on plates She has 63 spring rolls and 84 cheese cubes She wants to include both appetizers on each plate Each plate must have the same number of spring rolls and cheese cubes. What is the greatest number of plates she can make using all of the appetizers ? How of each type of appetizer on each plate?

Answer 1

The largest common factor for 63 and 84 is 21. This tells you the greatest number of plates she can make using all of the appetisers as both numbers divide cleanly by 21, so there will be no left overs. The factors you multiply by are 3, for 63, and 4, for 84. Thus, you can have 3 spring rolls and 4 cheese cubes on each plate.
