Hi there) In your example you explain how to calculate ratio metrics using denominators (first screenshot). But in your example you use the denominator “number of orders” which is count value. We need to use a little bit of other calculation. For example we have facebook_expenses = 16,5$ by month and total_advertisement_expenses = 990,6$ by month. These two metrics are revenue type metrics and our formula is next (we have continuous value in denominator). Can we calculate by our formula? facebook_expenses / total_advertisement_expenses

A revenue metric is basically just a count metric (you're counting dollars), so I think it should work. You'll need to make your

total_advertisement_expenses

metric have type

count

instead of revenue in order to select it as a denominator.
