The number of jelly beans that Julie had in the end is repeated. Make the number of jelly beans that Julie had in the end the same. LCM of 1 and 3 is 3.
Number of jelly beans that Nicole had less than Julie
= 15 u - 4 u
= 11 u
11 u = 33
1 u = 33 ÷ 11 = 3
Number of jelly beans that Julie had at first
= 15 u
= 15 x 3
= 45
Answer(s): 45
