First, change the mixed number to decimal by changing first the mixed number to improper fraction. To change into an improper fraction, multiply the denominator with the whole number then add it to the numerator:

Change 2 3/4 to percent:
 
    = 2 \frac{3}{4}  \frac{(2 x  4 ) + 3}{4}  \frac{11}{4}  

Change into decimal by dividing the numerator by the denominator of the improper fraction:
   
    =  \frac{11}{4} = 2.75

Now that you have the decimal, multiply it by 100 and change the decimal point into the percent symbol (%) :

2.75 x 100 = 275 or 275. = 275%

Answer:
              275%
