Answer 1

1.

4 w------------------------->6 g

x w------------------------->24 g

Using cross multiplication:

`\begin{gathered} (4)/(x)=(6)/(24) \\ \text{solve for x:} \\ x=(24*4)/(6) \\ x=16 \end{gathered}`

Answer: 16 white beads

2.

Express the percentage as a decimal:

52% = 52/100 = 0.52

Multiply this result by the total number of votes:

`250*0.52=130`

Gillian received 130 votes
