15 The number of green stickers is the repeated identity.
Make the number of green stickers the same using the LCM of 10 and 1.
LCM of 10 and 1 = 10
(a) Number of blue stickers = 10 u
(b) Number of red stickers = 50 u
(c) Total number of stickers = 1 u + 10 u + 50 u = 61 u
(d) Number of less green stickers than blue stickers = 10 u - 1 u = 9 u
Answer(s): (a) 10; (b) 50; (c) 61; (d) 9
