The total number of beads remains unchanged after Carl gives to Ethan.
Total number of beads
= 248 + 405
= 653
Total number of beads in the end
= 1 u + 1 u + 141
= 2 u + 141
2 u + 141 = 653
2 u = 653 - 141
2 u = 512
1 u = 512 ÷ 2 = 256
Number of beads that Carl must give to Ethan
= 256 - 248
= 8
Answer(s): 8
