910The number of square stickers in both albums is the same. Make the number of square stickers the same. LCM of 1 and 4 is 4.
Number of more round stickers in Album G than Album H
= 36 u - 1 u
= 35 u
35 u = 595
1 u = 595 ÷ 35 = 17
Number of stickers in both albums
= 36 u + 4 u + 1 u + 4 u
= 45 u
= 45 x 17
= 765
Answer(s): 765
