Fraction Multiplying and Dividing!



As in multiplication, we must change mixed numbers to improperfractions. The common denominator is this example is 4. To change a whole number into a fraction, multiply the whole number by the denominator. That product will be the numerator


  1. To multiply fractions:

    1. Simplify the fractions if not in lowest terms.
    2. Multiply the numerators of the fractions to get the new numerator.
    3. Multiply the denominators of the fractions to get the new denominator.


  1. There are 3 Simple Steps to add fractions:

    1. Step 1: Make sure the bottom numbers (the denominators) are the same.
    2. Step 2: Add the top numbers (the numerators), put the answer over the denominator.
    3. Step 3: Simplify the fraction (if needed)


  1. So, here are the steps.

    1. Build each fraction so that both denominators are equal. ...
    2. Re-write each equivalent fraction using this new denominator.
    3. Now you can subtract the numerators, and keep the denominator of the equivalent fractions.
    4. Re-write your answer as a simplified or reduced fraction, if needed.


  1. Equivalent fractions are fractions that may look different, but are equal to each other. Two equivalent fractions may have a different numerator and a different denominator. (A fraction is also equivalent to itself. In this case, the numerator and denominator would be the same.)
