The remaining number of stickers before Jean bought another 126 stickers is repeated. Make the remaining number of stickers the same. LCM of 3 and 5 is 15.
Total number of stickers at first = 20 u
Number of stickers that Jean had left and bought after that = 6 u + 126
20 u = 6 u + 126
20 u - 6 u = 126
14 u = 126
1 u = 126 ÷ 14 = 9
Total number of stickers at first
= 20 u
= 20 x 9
= 180
Answer(s): 180
