2. IMPORTANT VOCABULARY NUMERATOR –
the number above the line in a common fraction showing how many of the parts indicated by the denominator are taken. Ex. 1 5
DENOMINATOR –
the number below the line in a common fraction; a divisor.
a figure representing the total population in terms of which statistical values are expressed. Ex. 1 5
MIXED FRACTION –
a fraction where a whole number is combined with a fraction. Ex

3. IMPORTANT VOCABULARY IMPROPER FRACTION –
a fraction where the numerator’s value is greater than the denominator’s value. Ex. 5 1
COMMON DENOMINATOR –
a situation where 2 or more fractions have the same values as their denominators. Ex
RECIPROCOL –
where you flip the numerator for the denominator and vise versa. Ex becomes 5 1

4. ADDING
STEP 1: convert all fractions so that their DENOMINATORS ARE COMMON
STEP 2: ADD ONLY THE NUMERATORS
STEP 3: bring to lowest terms if appropriate
(x 4) (x 5)
Example: =

5. SUBTRACTING
STEP 1: convert all fractions so that their DENOMINATORS ARE COMMON
STEP 2: SUBTRACT ONLY THE NUMERATORS
STEP 3: bring to lowest terms if appropriate
(x 4) (x 5)
Example: =

6. MULTIPLYING STEP 1: MULTIPLY ONLY THE NUMERATORS
STEP 2: MULTIPLY ONLY THE DENOMINATORS
STEP 3: bring to lowest terms if appropriate
Example: x =

7. DIVIDING
STEP 1: convert the fraction AFTER THE SIGN to its reciprocol.
STEP 2: FOLLOW MULTIPLICATION RULES
STEP 3: bring to lowest terms if appropriate
Example: ÷ X = 8 5
