0.5 =
510 =
12 Fraction of beads that are white and silver beads
= 1 -
12 =
12 Total number of beads = 2 u
2 u = 144
1 u = 144 ÷ 2 = 72
Number of white beads and silver beads
= 1 u
= 1 x 72
= 72
Number of white and silver beads
= 1 p + 7 p
= 8 p
8 p = 72
1 p = 72 ÷ 8 = 9
Number of silver beads
= 7 p
= 7 x 9
= 63
Answer(s): 63
