Make the number of green stickers the same using the LCM of 1 and 3.
LCM of 1 and 3 = 3
(a) Number of blue stickers = 12 u
(b) Number of red stickers = 10 u
(c) Total number of stickers = 12 u + 3 u + 10 u = 25 u
(d) Number of more blue stickers than red stickers = 12 u - 10 u = 2 u
Answer(s): (a) 12; (b) 10; (c) 25; (d) 2
