AFTER SOLVING ADDITION OR SUBTRACTION OF
FRACTIONS-ALL ANSWERS MUST BE IN SIMPLEST
do you find Simplest Form?
Find your GCF (Greatest Common Factor) See example below:
fraction is 3/12 You want to find the simplest form:
1: Find your GCF by listing the
factors for your numerator 3 and your denominator 12
2: Now take your GCF and divide
the numerator and the denominator by the GCF.
divided by 3/3=1/4
3/12 in simplest form = 1/4 Viola!
WHAT DO YOU DO WHEN YOU WANT TO ADD OR
SUBTRACT FRACTIONS WITH DIFFERENT (UNLIKE) DENOMINATORS?
may not add or subtract fractions without first finding their LCD (lowest
common denominator). They must have the same denominator in order for
you to add or subtract them.
do you find your LCD? By
finding your LCM (lowest common multiple)
3/4 + 3/6
One: Take the two denominators
4 and 6 and list all their multiples until you find the LCM
12 Your LCM=12, therefore your LCD=12
Two: 3/4 x 3/3=9/12 and 3/6 x
2/2= 6/12 Now you are ready to add. 9/12 + 6/12= 15/12
Three: 15/12 is an IMPROPER
FRACTION. YOU MUST SIMPLIFY IT by dividing
divided by 12= 1 remainder 3, this transforms into a MIXED NUMBER OF 1 3/12
And in SIMPLEST FORM 1 AND 3/12 EQUALS 1
