Tricks

1. Cancel out common factors between numerators and a denominators before performing division.
2. Also cancel out common factors across the numerator of one fraction with the denominator of another to simplify calculations.
3. Ensure that the result is always greater than the original numerator but less than the original denominator, because the result represents how many times one fraction fits into another.

Rules

1. Convert the operation to multiplication before performing any cancellations.
2. Remember to only invert the divisor when performing division.
3. Ensure that neither the numerator nor the denominator of the divisor is zero to avoid undefined results.
