0.2 =
210 =
15 Fraction of beads that are silver and gold beads
= 1 -
15 =
45 Total number of beads = 5 u
5 u = 175
1 u = 175 ÷ 5 = 35
Number of silver beads and gold beads
= 4 u
= 4 x 35
= 140
Number of silver and gold beads
= 1 p + 4 p
= 5 p
5 p = 140
1 p = 140 ÷ 5 = 28
Number of gold beads
= 4 p
= 4 x 28
= 112
Answer(s): 112
