  1. Changing Mixed Numbers to Improper Fractions and Improper Fractions to Mixed Numbers

  2. Change a Mixed Number to an Improper Fraction • Multiply whole number by denominator of the fraction • Add the numerator • Put the sum over the given denominator

  3. Change an Improper Fraction to a Mixed Number • Divide the numerator by the denominator • The whole number becomes the whole number part of the mixed number • The remainder becomes the numerator • Denominator stays the same • Simplify!

  4. Subtracting from Whole Numbers

  5. To Subtract a Fraction from a Whole Number: • Rewrite the whole number as a mixed number (fractions should have the same denominators) • Then subtract

  6. Adding and Subtracting Mixed Numbers

  7. Adding Mixed Numbers When the denominators are the same: • Add the fractions • Add the whole numbers • Simplify

  8. Adding Mixed Numbers When the denominators are different: • Find the LCD of the fractions and rewrite as equivalent fractions • Add the fractions • Add the whole numbers • Simplify

  9. Subtracting Mixed Numbers With like denominators: • Subtract the fractions • Subtract the whole numbers • Simplify

  10. Subtracting Mixed Numbers When the denominators are different: • Find the LCD and rewrite fractions as equivalent fractions • Subtract fractions • Subtract whole numbers • Simplify
