0.3 =
310 =
310 Fraction of beads that are silver and blue beads
= 1 -
310 =
710 Total number of beads = 10 u
10 u = 130
1 u = 130 ÷ 10 = 13
Number of silver beads and blue beads
= 7 u
= 7 x 13
= 91
Number of silver and blue beads
= 3 p + 4 p
= 7 p
7 p = 91
1 p = 91 ÷ 7 = 13
Number of blue beads
= 4 p
= 4 x 13
= 52
Answer(s): 52
