0.3 =
310 =
310 Fraction of beads that are white and pink beads
= 1 -
310 =
710 Total number of beads = 10 u
10 u = 120
1 u = 120 ÷ 10 = 12
Number of white beads and pink beads
= 7 u
= 7 x 12
= 84
Number of white and pink beads
= 1 p + 5 p
= 6 p
6 p = 84
1 p = 84 ÷ 6 = 14
Number of pink beads
= 5 p
= 5 x 14
= 70
Answer(s): 70
