12 Fraction of beads that are yellow and white beads
= 1 -
12 =
12 Total number of beads = 2 u
2 u = 120
1 u = 120 ÷ 2 = 60
Number of yellow beads and white beads
= 1 u
= 1 x 60
= 60
Number of yellow and white beads
= 3 p + 7 p
= 10 p
10 p = 60
1 p = 60 ÷ 10 = 6
Number of white beads
= 7 p
= 7 x 6
= 42
