Nigeria international, Joe Aribo, opened scoring for his side, Rangers, first time he returned to the pitch where he had to be stretchered away after a horrific head injury.
Assisted by Scott Arfield, Aribo’s left footed shot from the centre of the box settled into the top left corner of the post for the first goal of the match.
Alfredo Morelos added a second as the visitors eased to the points.
Rangers remain level on points with Celtic at the top of the Scottish Premiership after sweeping aside Livingston at the Tony Macaroni Arena.
But with Celtic matching the scoreline in their win over Motherwell, Rangers go into the international break second in the table on goal difference.
