Question 116601
10.50 % of 22 = (10.50/100)*22
              =  0.1050 * 22
              =  2.31

Just now i came to know that 10 is the question number and not a part of question...
Hence, the answer goes like this...

50% of 22 = (50/100)*22
          = 0.50 * 22
          = 11

Devnull, hope your problem is solved.
