The answer is 11/50. To find a simple form of a fraction, we must simplify either divisor or dividend to a prime number. If we take a look at the fraction 22/100, we can see that dividend if divided by 2 will be 11 which is the prime number. Therefore, let's divide both divisor and dividend by 2: 22/100 = (22:2)/(100:2) = 11/50.
