12 The number of green stickers is the repeated identity.
Make the number of green stickers the same using the LCM of 5 and 1.
LCM of 5 and 1 = 5
(a) Number of red stickers = 5 u
(b) Number of blue stickers = 10 u
(c) Total number of stickers = 2 u + 5 u + 10 u = 17 u
(d) Number of less green stickers than red stickers = 5 u - 2 u = 3 u
Answer(s): (a) 5; (b) 10; (c) 17; (d) 3
