Fraction Multiplying and Dividing!
By BRANDON AND AArON
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
Multiplying
To multiply fractions:
- Simplify the fractions if not in lowest terms.
- Multiply the numerators of the fractions to get the new numerator.
- Multiply the denominators of the fractions to get the new denominator.
Adding?!
There are 3 Simple Steps to add fractions:
- Step 1: Make sure the bottom numbers (the denominators) are the same.
- Step 2: Add the top numbers (the numerators), put the answer over the denominator.
- Step 3: Simplify the fraction (if needed)
Subtractin!
So, here are the steps.
- Build each fraction so that both denominators are equal. ...
- Re-write each equivalent fraction using this new denominator.
- Now you can subtract the numerators, and keep the denominator of the equivalent fractions.
- Re-write your answer as a simplified or reduced fraction, if needed.
Equivalent!
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.)
