310 The number of blue stickers is the repeated identity.
Make the number of blue stickers the same using the LCM of 4 and 3.
LCM of 4 and 3 = 12
(a) Number of red stickers = 12 u
(b) Number of green stickers = 40 u
(c) Total number of stickers = 3 u + 12 u + 40 u = 55 u
(d) Number of less blue stickers than red stickers = 12 u - 3 u = 9 u
Answer(s): (a) 12; (b) 40; (c) 55; (d) 9
