25 The number of green stickers is the repeated identity.
Make the number of green stickers the same using the LCM of 4 and 2.
LCM of 4 and 2 = 4
(a) Number of red stickers = 4 u
(b) Number of blue stickers = 10 u
(c) Total number of stickers = 1 u + 4 u + 10 u = 15 u
(d) Number of more blue stickers than red stickers = 10 u - 4 u = 6 u
Answer(s): (a) 4; (b) 10; (c) 15; (d) 6
