How do you simplify a ratio that has mixed units?

I'm guessing by mixed units you mean 30cm:5m or similar? If so you need to convert them to the same unit so either 0.3:5 or 30:500

I hope this helps. If you have any further questions please don't hesitate to ask.

If a ratio has mixed units you must first convert all the units to the same type. Then you can try to simplify it if the parts have common factors by dividing by the common factors.
