Denny has a carton of apples. There are fewer than 45 apples in the carton. The number of apples in the carton can be packed into bags of 3 or 5. What is the greatest possible number of apples in the carton?
This is gcf or lcm problem...Dont know which one, but
There are less than 45 apples, but the number is divisible by both 3 and 5. This will mean it is divible by 15 too. if 45 is not an option, we will look at the next greatest multiple of 15 under that which is 30. 30 is the greatest possible number of apples.
