The remaining number of stickers before Diana bought another 95 stickers is repeated. Make the remaining number of stickers the same. LCM of 5 and 4 is 20.
Total number of stickers at first = 24 u
Number of stickers that Diana had left and bought after that = 5 u + 95
24 u = 5 u + 95
24 u - 5 u = 95
19 u = 95
1 u = 95 ÷ 19 = 5
Total number of stickers at first
= 24 u
= 24 x 5
= 120
Answer(s): 120
