0.5 =
510 =
12 Fraction of beads that are red and silver beads
= 1 -
12 =
12 Total number of beads = 2 u
2 u = 150
1 u = 150 ÷ 2 = 75
Number of red beads and silver beads
= 1 u
= 1 x 75
= 75
Number of red and silver beads
= 1 p + 4 p
= 5 p
5 p = 75
1 p = 75 ÷ 5 = 15
Number of silver beads
= 4 p
= 4 x 15
= 60
Answer(s): 60
