1 u |
The number of lollipops that Irene had in the end is repeated. Make the number of lollipops that Irene had in the end the same. LCM of 1 and 3 is 3.
Number of lollipops that Wendy had less than Irene
= 12 u - 4 u
= 8 u
8 u = 80
1 u = 80 ÷ 8 = 10
Number of lollipops that Irene had at first
= 12 u
= 12 x 10
= 120
Answer(s): 120
