There are 20 teachers and 705 students in cory's school. what is the ratio of teachers and students
Aleksandr [31]

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

What is the original number if 9/10 of the number is 90?
coldgirl [10]
It would be 100. If you divide 100/10, you get 10, multiply that by 9 and you’d get 90.
