0.4 =
410 =
25 Fraction of beads that are blue and silver beads
= 1 -
25 =
35 Total number of beads = 5 u
5 u = 160
1 u = 160 ÷ 5 = 32
Number of blue beads and silver beads
= 3 u
= 3 x 32
= 96
Number of blue and silver beads
= 1 p + 7 p
= 8 p
8 p = 96
1 p = 96 ÷ 8 = 12
Number of silver beads
= 7 p
= 7 x 12
= 84
Answer(s): 84
