910The number of square stickers in both albums is the same. Make the number of square stickers the same. LCM of 1 and 3 is 3.
Number of more oval stickers in Album L than Album M
= 27 u - 1 u
= 26 u
26 u = 364
1 u = 364 ÷ 26 = 14
Number of stickers in both albums
= 27 u + 3 u + 1 u + 3 u
= 34 u
= 34 x 14
= 476
Answer(s): 476
