0.5 =
510 =
12 Fraction of beads that are grey and yellow beads
= 1 -
12 =
12 Total number of beads = 2 u
2 u = 120
1 u = 120 ÷ 2 = 60
Number of grey beads and yellow beads
= 1 u
= 1 x 60
= 60
Number of grey and yellow beads
= 1 p + 4 p
= 5 p
5 p = 60
1 p = 60 ÷ 5 = 12
Number of yellow beads
= 4 p
= 4 x 12
= 48
Answer(s): 48
