QuestionIf 45 students attend, how many adults are needed if the ratio of adults to students is 2 to 9? Use a tape diagram and ratio table.

Studdy Solution
For the ratio table, we can start with the ratio2 and scale up to the number of students (45). The table would look something like this$\begin{array}{|c|c|} \hline\text{Adults} & \text{Students} \\ \hline2 & \\ \hline4 &18 \\ \hline6 &27 \\ \hline8 &36 \\ \hline10 &45 \\ \hline\end{array}$
As we can see, when there are45 students, there are10 adults, which matches our earlier calculation.
