Percent of Total based on Dynamic Filters

Hi All,

 I'm fairly new to the world of Power BI and just created some new dashboards. I have a quick question on how to display the % of total and this % changing based on the filter I select.

 For example, I want to calculate % of 22/35 and show this on my dashboard. So, I want the dashboard to show 63%; however, when I select a filter, the numbers change to 3/35. How can I set up a formula to show 63% and then as I click on filters, the % value to change accordingly?

 Any assistance would be greatly and sincerely appreciated.
