0.5 =
510 =
12 Fraction of beads that are silver and green beads
= 1 -
12 =
12 Total number of beads = 2 u
2 u = 180
1 u = 180 ÷ 2 = 90
Number of silver beads and green beads
= 1 u
= 1 x 90
= 90
Number of silver and green beads
= 1 p + 8 p
= 9 p
9 p = 90
1 p = 90 ÷ 9 = 10
Number of green beads
= 8 p
= 8 x 10
= 80
Answer(s): 80
