25 The number of green stickers is the repeated identity.
Make the number of green stickers the same using the LCM of 10 and 2.
LCM of 10 and 2 = 10
(a) Number of red stickers = 10 u
(b) Number of blue stickers = 25 u
(c) Total number of stickers = 3 u + 10 u + 25 u = 38 u
(d) Number of less green stickers than red stickers = 10 u - 3 u = 7 u
Answer(s): (a) 10; (b) 25; (c) 38; (d) 7
