Steps
When using the Butterfly method, What is the 1st step when solving addition and subtraction problems with unlike denominators?
Draw the wings and get ready to cross multiply
1/2 + 1/2 =
2/2 or 1
1/4 + 2/6
14/24 or 7/12
What is the 2nd step when adding/subtracting fractions with unlike denominators?
Multiply the wings and write the answer on the antennas.
1/1 + 1/6 =
7/6 or 1 1/6
What is the 3rd step when adding and subtracting fractions with unlike denominators?
Add a body and multiply the denominators. This will be your new denominator.
What is the 4th step when adding and subtracting fractions with unlike denominators?
Add or subtract the antennas, this will be your numerator.
6/12 + 4/12 =
10/12 or 5/6
List the 4 steps when adding and subtracting fractions with unlike denominators.
1. Draw the wings 2. multiply the wings and write the answers on the antennas 3. Draw a body, connecting the denominators. Multiply the denominators. This will be your new denominator. 4. Add/Subtract the antennas to get your numerator.
