We know that the relationship between doubles and total is 5: 1, therefore, we can estimate the times that doubles would come out knowing that the total is 450, by proportion we calculate:

[tex]\begin{gathered} \frac{1}{5}=\frac{x}{450} \\ \text{ Solving for x:} \\ x=\frac{450}{5} \\ x=90 \end{gathered}[/tex]

Therefore, the number of doubles expected is 90
