Trent has some yellow, red, green, and blue cubes. Exactly 1/5 of the cubes are yellow and 1/6 of the cubes are green. Which of these numbers of cubes might Trent have

Answer 1

It’s 30 cubes! Not any other answer.

Answer 2

Trent has at least 30 cubes.

Explanation:

This is because the lowest common multiple of both 5 and 6 is 30. In order for you to get fractions with those denominators, there would have to be a total number in which they share the multiple.
