Comparing Fractions
Tips: just bear in mind a few simple rules:Same numerator, fraction with a larger denominator is smaller
Same denominator, fraction with a smaller numerator is smaller
Same difference between denominator and numerator, fraction with larger numbers is bigger (assuming they are less than 1. Otherwise, the conclusion is reversed)
If two fractions share nothing in common, cross-multiplying them, whichever side ends up bigger is bigger
