15 The number of blue stickers is the repeated identity.
Make the number of blue stickers the same using the LCM of 10 and 1.
LCM of 10 and 1 = 10
(a) Number of red stickers = 10 u
(b) Number of green stickers = 50 u
(c) Total number of stickers = 3 u + 10 u + 50 u = 63 u
(d) Number of less blue stickers than red stickers = 10 u - 3 u = 7 u
Answer(s): (a) 10; (b) 50; (c) 63; (d) 7
