Answer #1

Note that      
      
1/f = 1/do + 1/di      
      
where      
      
f = focal length =    13.4   cm
do = object distance =    52   cm
di = image distance      
      
Thus, solving for di,      
      
di =    18.05    cm   [ANSWER, PART 1]
      
Thus, the magnification, m = -di/do,      
      
m =    -0.347    [ANSWER, PART 2]
