| 2 u |
3 u |
5 u |
| |
1 p |
8 p |

0.4 =
410 =
25 Fraction of beads that are white and blue beads
= 1 -
25 =
35 Total number of beads = 5 u
5 u = 120
1 u = 120 ÷ 5 = 24
Number of white beads and blue beads
= 3 u
= 3 x 24
= 72
Number of white and blue beads
= 1 p + 8 p
= 9 p
9 p = 72
1 p = 72 ÷ 9 = 8
Number of blue beads
= 8 p
= 8 x 8
= 64
Answer(s): 64
