34 The number of green stickers is the repeated identity.
Make the number of green stickers the same using the LCM of 5 and 3.
LCM of 5 and 3 = 15
(a) Number of red stickers = 15 u
(b) Number of blue stickers = 20 u
(c) Total number of stickers = 3 u + 15 u + 20 u = 38 u
(d) Number of less green stickers than red stickers = 15 u - 3 u = 12 u
Answer(s): (a) 15; (b) 20; (c) 38; (d) 12
