Answer:
The smallest number of each color Emma could buy is 5 packs of purple beads, 8 packs of red beads, and 4 bags of blue beads.
Explanation:
The LCM of 5, 8, and 10 is 40.
To find out the least amount of bags Emma could buy, you would need to multiply each number of beads by a number to make 40, which is the LCM
For example,
8 x 5 = 40
5 x 8 = 40
10 x 4 = 40.
