Answer:

50

Step-by-step explanation:

given that

12 \frac{1}{2} \%of \: 400

Solution

as here mixed fraction is given hence need to convert it into fraction as follow we get

 \frac{24 + 1}{2} \%of \: 400

we get

 \frac{25}{2} \%of \: 400

12.5\%of \: 400

as % can be written as

 \frac{12.5}{100}  \times 400

by multiplication we get

12.5 \times 4

we get

 = 50

hence 50 is the solution.
