Make the number of red stickers the same using the LCM of 5 and 1.
LCM of 5 and 1 = 5
(a) Number of blue stickers = 5 u
(b) Number of green stickers = 50 u
(c) Total number of stickers = 2 u + 5 u + 50 u = 57 u
(d) Number of less red stickers than blue stickers = 5 u - 2 u = 3 u
Answer(s): (a) 5; (b) 50; (c) 57; (d) 3
