12 Fraction of beads that are white and brown beads
= 1 -
12 =
12 Total number of beads = 2 u
2 u = 154
1 u = 154 ÷ 2 = 77
Number of white beads and brown beads
= 1 u
= 1 x 77
= 77
Number of white and brown beads
= 3 p + 4 p
= 7 p
7 p = 77
1 p = 77 ÷ 7 = 11
Number of brown beads
= 4 p
= 4 x 11
= 44
Answer(s): 44
