Make the number of green stickers the same using the LCM of 2 and 3.
LCM of 2 and 3 = 6
(a) Number of blue stickers = 6 u
(b) Number of red stickers = 20 u
(c) Total number of stickers = 3 u + 6 u + 20 u = 29 u
(d) Number of more red stickers than blue stickers = 20 u - 6 u = 14 u
Answer(s): (a) 6; (b) 20; (c) 29; (d) 14
