11/22 = 50%
The fraction 11/22 represents 50%, or one-half. You might see this in everyday life when half of a class chooses pizza, half of a sale price is taken off, or half a tank of gas remains.
To picture 11/22 quickly, imagine dividing something into two equal groups and focusing on one group. Since the numerator is exactly half of the denominator, you can estimate it as about half without doing any detailed work.
A common mistake is thinking that 11/22 is less than one-half because both numbers are fairly large. The numbers can be reduced by the same amount, but the value stays the same: it is still exactly 50%.
