1x3 =
3 u |
The number of beads that Hazel had at first and in the end remains unchanged. Make the number of beads that Hazel had the same. LCM of 15 and 5 is 15.
Number of beads that Hazel had more than Tiffany at first
= 15 u - 4 u
= 11 u
11 u = 121
1 u = 121 ÷ 11 = 11
Number of beads that Tiffany had at first
= 4 u
= 4 x 11
= 44
Answer(s): 44
