The number of beads that Natalie had at first and in the end remains unchanged. Make the number of beads that Natalie had the same. LCM of 8 and 2 is 8.
Number of beads that Natalie had more than Sabrina at first
= 8 u - 5 u
= 3 u
3 u = 135
1 u = 135 ÷ 3 = 45
Number of beads that Sabrina had at first
= 5 u
= 5 x 45
= 225
Answer(s): 225
