Calculating quotient between columns

[moiran]

I'm really new to Power BI, trying to wrap my head around how I'm supposed to go about stuff. 

I have a table with two calculated columns: Registered hours and Invoiced hours, both containing decimal numbers.

I want to create a Card Visual that shows the quotient between the sums of these columns (Invoiced hours/Registered hours). How can I do that?

@moiran - In your data model (table looking icon on the left), click "New Measure". Then, use the following formula:

Measure = SUM([Invoiced hours]) / SUM([Registered hours])

Then, put that measure in your card visual.

It's so simple once someone explains it to you... Thank you!
