Sum of percentage

Hi everyone! Is Power Bi capable to sum percentage to get total percentage based on percentage measure calculation. I have 2 measures, REJECT_YDA & BGRADE_YDA. The measure is like this;

REJECT_YDA =

CALCULATE(DIVIDE( [TOTAL_REJECT], [TOTAL_PRD] ), 'Calendar'[Yesterday Equal Today] = TRUE() ).

Is is possible for me to make a sum like function to this measure to total up the values? for example is BGRADE_YDA, the total is 0.02% for values 0.05% and 0.08%. It is auto calculated by power bi. But i want like an absolute total like if i plus 0.05 + 0.08 = 0.13 right? not 0.02.

Really appreciate if anyone can share something to a newbie like me. Thanks in advanced!
