Determine the percentage of students seen in both cases.
This percentage is calculated by dividing the number of students seen by the total number of students. Then multiplied by 100%
i.e
![\%Percent = (Seen)/(Total) * 100\%](https://img.qammunity.org/2021/formulas/mathematics/college/5atpl1mmp1oboxnk6t9uqy5sdpa8073oso.png)
- Before Lunch;
![\%Percent = (Before\ Lunch)/(Total) * 100\%](https://img.qammunity.org/2021/formulas/mathematics/college/dq84qy9vvnn4f5xzs0qkzaziip8i6x8cc8.png)
![\%Percent = (38)/(134) * 100\%](https://img.qammunity.org/2021/formulas/mathematics/college/rvqkz8rvcakqvaj94gax3rsz822liolsl5.png)
![\%Percent = (3800\%)/(134)](https://img.qammunity.org/2021/formulas/mathematics/college/o47io5ac0ym8p6vft11sjnacembp7815mz.png)
