0.2 =
210 =
15 Fraction of beads that are red and green beads
= 1 -
15 =
45 Total number of beads = 5 u
5 u = 130
1 u = 130 ÷ 5 = 26
Number of red beads and green beads
= 4 u
= 4 x 26
= 104
Number of red and green beads
= 3 p + 5 p
= 8 p
8 p = 104
1 p = 104 ÷ 8 = 13
Number of green beads
= 5 p
= 5 x 13
= 65
Answer(s): 65
