Hello @alexbeyman, dont worry, you have confusion in understanding the 50/50 ratio. And please note the following :-
(1)the first half is given in SBD, in the exact amount shown by division. In our case, half of 75 is 37.5. So you get half of your rewards as 37.5 SBD
(2)the second half is given in Steem Power, at the current feed price (the internal Steemit price for STEEM) in USD. So you get $37.5 worth of Steem Power. If the current feed price of STEEM is, let's say $6, you get $37.5 / $6 = 6.25 Steem Power.
To know in details please visit the following post where complete explanation is given.
Thanks...steem on...and stay blissul...
