0.5 =
510 =
12 Fraction of beads that are purple and yellow beads
= 1 -
12 =
12 Total number of beads = 2 u
2 u = 192
1 u = 192 ÷ 2 = 96
Number of purple beads and yellow beads
= 1 u
= 1 x 96
= 96
Number of purple and yellow beads
= 1 p + 5 p
= 6 p
6 p = 96
1 p = 96 ÷ 6 = 16
Number of yellow beads
= 5 p
= 5 x 16
= 80
Answer(s): 80
