title: How to create a new column to calculate percentage weight of a value in power bi
body: <p>I am trying to achieve Percentage_weight from 4 different columns of a table into a new column. This is what I can do in Excel <code>=SUM((D2*0.2)+(E2*0.25)+(F2*0.25)+(G2*0.3))</code>.</p>
  <p>How do we do the same calculations in Power BI?</p>
