1 u |
The number of lollipops that Nora had in the end is repeated. Make the number of lollipops that Nora had in the end the same. LCM of 1 and 3 is 3.
Number of lollipops that Nicole had less than Nora
= 24 u - 5 u
= 19 u
19 u = 76
1 u = 76 ÷ 19 = 4
Number of lollipops that Nora had at first
= 24 u
= 24 x 4
= 96
Answer(s): 96
