Find the z value to the right of the mean so that 
Use the Inverse Norm function on calculator or Use a table:
 a. 53.98% of the area under the normal distribution curve lies to the left of it. InvNorm(.5396) = .0994
 b. 71.90% of the area under the normal distribution curve lies to the left of it. InvNorm(.7190) = .5799
 c. 96.78% of the area under the normal distribution curve lies to the left of it. InvNorm(.9678) = 1.8494
