you round fractions by rounding up or down, you can decide to do this when you look at the numerator and decide if it is half of the denominator, if it is half or more than half, you round up. If it is less than half you round down.
Another way you can round fractions is dividing the top number by the bottom number (with a calculator), then if the decimal part is 5 or more, round up! (if the decimal is less than 5, round down.)
