Question

There are 20 teachers and 705 students in cory's school. what is the ratio of teachers and students

Answer 1

We know that ratios can be shown with both fractions and colons.

20:705

or

$\frac{20}{705}$

It also looks like we can simplify this by dividing by 5.

20/5 = 4

705/5 = 141.

This means that for every 4 teachers, there are 141 students.

The ratio for teachers to students is:

4 : 141
