• Fractions consist of two
numbers. The top
number isnumerator
called the
. The bottom number is
denominator.
called the
Adding Fractions
To add two
fractions with the
same denominator
*add the numerators
*place that sum over
the common
denominator
To add fractions with
different
denominators:
*find the Least
Common
Denominator (LCD) of
the fractions
*rename the fractions
to have the LCD
*add the numerators
of the fractions
Subtracting Fractions
To subtract two fractions
with the same
denominator
*subtract the numerators
*place that difference over the
common denominator.
To Subtract Fractions with
different denominators:
*Find the Lowest Common
Denominator (LCD) of the fractions
*Rename the fractions to have the
LCD
*Subtract the numerators of the
fractions The difference will be the
numerator and the LCD will be the
denominator of the answer.
*Simplify the Fraction
Multiplying Fractions
To Multiply Fractions:
Multiply the
numerators of the
fractions
Multiply the
denominators of the
fractions
Place the product of
the numerators over
the product of the
denominators
Simplify the Fraction
Dividing Fractions
To Divide Fractions:
Invert (i.e. turn over)
the denominator
fraction and multiply
the fractions
Multiply the
numerators of the
fractions
Multiply the
denominators of the
fractions
Place the product of
the numerators over
the product of the
denominators
Simplify the Fraction
