To determine

To calculate: To find which of the jobs has the largest percentage of student workers

Answer to Problem 7.2MPS

The largest percentage of student workers worked in fast food

Explanation of Solution

Given information: A recent survey of students with part-time jobs showed that $33\%$ worked in grocery store, $\frac{7}{20}$ worked in fast food and $0.27$ worked in childcare

Formula Used:

To convert decimal into percent, multiply the decimal number by $100$ and put the $\%$ sign

Calculation:

Given that in a recent survey of students with part-time jobs showed that $33\%$ worked in grocery store, $\frac{7}{20}$ worked in fast food and $0.27$ worked in childcare

Now, student who worked in fast food

  $\frac{7}{20}$

On converting into percentage

  $\begin{array}{l}\frac{7}{20}=\frac{7}{20}\times 100\\ \frac{7}{20}=7\times 5\\ \frac{7}{20}=35\%\end{array}$

Also, student who worked in childcare

  $0.27$

On converting into percentage

  $\begin{array}{l}0.27=0.27\times 100\\ 0.27=27\%\end{array}$

Thus, thelargest percentage of student workers worked in fast food

Conclusion:

Hence, the largest percentage of student workers worked in fast food
