Verified Answer :

 For this case we have the following expression:

 45 1/2%

 Rewriting in decimal form we have:

 45.5%

 Then, the percentage in its numerical and decimal form is:

 \(45.5 * (1/100) = 0.455\)
 We now write the decimal in the form of a fraction.

 We have then:

 \(0.455 * (1000/1000) = 455/1000\)
 Simplifying the fraction we have:

 \((455/1000) * ((1/5) / (1/5)) = 91/200\)
 Answer:

 The expression given in the form of fraction is:

 91/200
