40. Mari has 42 green beads, 30 yellow beads, and 54 blue beads. She wants to use all of the beads and string the beads so that she has the same number of each color on a string of beads. What is the greatest number of strings of beads she can make?
30 because she has 30 yellow beads and we can take away 30 from the other numbers. So 30 is the greatest number of strings of beads she can make. Hope this helped,have a great day!
