Since there are 4 students at each thable, we know that the ratio tables to students is:
![\frac{\text{tables}}{\text{students}}=(1)/(4)](https://img.qammunity.org/2023/formulas/mathematics/college/z1erehs0hu8z6vmeisgstkgump34afwdsh.png)
Then, if we want to find the amount of tables that we nee for a number n of students, we multiply n by the ratio we found, like this:
![\\u\text{mer of tables for n students=n}*(1)/(4)](https://img.qammunity.org/2023/formulas/mathematics/college/cm809qdmm6ip7kspssbggo14hm19d8wgbz.png)
In this case, we want to fi
