  1. Fractions Rules for Avoiding Common Errors

  2. Simplifying Reduce = = = 10 = Greatest Common Factor Write the numerator and denominator as a product of factors, then cancel common factors and obtain the result.

  3. Simplifying = = = = Write the numerator and denominator as a product of common factors then cancel the common factors and obtain the result. Repeat the simplification process until all common factors are removed.

  4. Converting Mixed Numbers 1 1 5 5 3 3 3 3 + 16 = 3 Multiply the whole number by the denominator Add the numerator to the result Place over the initial denominator Compute the final result

  5. Converting Mixed Numbers 2 2 6 6 9 9 9 9 + 56 = 9 Multiply the whole number by the denominator Add the numerator to the result Place over the initial denominator Compute the final result
