How do I find the ratio of something?

The problem

You need to type down '7.5/8.75' or '7.5:8.75' into the solver to find the ratio:

7.5/8.5 = 6/7

You will get the same if you type:

7.5:8.75 = 6/7

If you need a decimal solution, go to 'Options' tab and select 'Calculate using: real (decimal) numbers' and you will get

7.5:8.75 = 0.857142857
