To convert the fraction to a percent, first convert it to a decimal by dividing the numerator by the denominator;
 
31 ÷ 4 = 7.75

Now to convert the decimal to a percent simply just move the decimal point two times to the right and add the percent sign;

7.75 ⇒ 775%
hope that helps :D
if you meant 31/4 as a percentage, here's how you have to do it,

to convert a fraction to a percentage, the denominator should be 100, so in this question you have to make 4,100.and if you do something to the denominator, same should be done to the numerator.

31×25/4×25
=775/100

so answer is 775%
hope this helps.....
