15 The number of red stickers is the repeated identity.
Make the number of red stickers the same using the LCM of 4 and 1.
LCM of 4 and 1 = 4
(a) Number of blue stickers = 4 u
(b) Number of green stickers = 20 u
(c) Total number of stickers = 1 u + 4 u + 20 u = 25 u
(d) Number of less red stickers than blue stickers = 4 u - 1 u = 3 u
Answer(s): (a) 4; (b) 20; (c) 25; (d) 3
