310 The number of red stickers is the repeated identity.
Make the number of red stickers the same using the LCM of 4 and 3.
LCM of 4 and 3 = 12
(a) Number of blue stickers = 12 u
(b) Number of green stickers = 40 u
(c) Total number of stickers = 9 u + 12 u + 40 u = 61 u
(d) Number of less red stickers than blue stickers = 12 u - 9 u = 3 u
Answer(s): (a) 12; (b) 40; (c) 61; (d) 3
