Question

Emilio and Jeremiah are studying a set of new words for Spanish class. Emilio decides to break the set into lists of 5 words. Meanwhile, Jeremiah creates lists of 9 words. What is the smallest number of words there could be?

Answer 1

To know what is the smallest number of words that should be in this list, the least common multiple must be calculated.

In this case the value is 45 because it is the minimum number that 5 and 9 have in common.
