The total number of sweets remains unchanged after Ethan gives to Jack.
Total number of sweets
= 480 + 523
= 1003
Total number of sweets in the end
= 1 u + 1 u + 59
= 2 u + 59
2 u + 59 = 1003
2 u = 1003 - 59
2 u = 944
1 u = 944 ÷ 2 = 472
Number of sweets that Ethan must give to Jack
= 523 - 472
= 51
Answer(s): 51
