25 The number of red stickers is the repeated identity.
Make the number of red stickers the same using the LCM of 5 and 2.
LCM of 5 and 2 = 10
(a) Number of blue stickers = 10 u
(b) Number of green stickers = 25 u
(c) Total number of stickers = 2 u + 10 u + 25 u = 37 u
(d) Number of less red stickers than blue stickers = 10 u - 2 u = 8 u
Answer(s): (a) 10; (b) 25; (c) 37; (d) 8
