0.3 =
310 =
310 Fraction of beads that are pink and silver beads
= 1 -
310 =
710 Total number of beads = 10 u
10 u = 160
1 u = 160 ÷ 10 = 16
Number of pink beads and silver beads
= 7 u
= 7 x 16
= 112
Number of pink and silver beads
= 3 p + 5 p
= 8 p
8 p = 112
1 p = 112 ÷ 8 = 14
Number of silver beads
= 5 p
= 5 x 14
= 70
Answer(s): 70
