Work Step by Step

We often express ratios as fractions. If we have 16 math teachers for 1856 math students, we set the ratio this way: $\frac{16}{1856}$ Next, we divide both the numerator and the denominator by their greatest common factor, which is $16$: $\frac{1}{116}$ This is the simplest we can make this ratio. It means that there is one math teacher for every 116 math students.
