Adding and Subtracting Fractions as Integers
Things to look for first
1) Are the denominators the same?
2) Are there mixed fractions I should change into improper fractions?
3) Can I clean up the equation? (get rid of extra + and signs)
Adding and Subtracting Fractions as Integers
Then check: Are the signs attached to the fraction the exact same or different?
1) If they are the same: I can add those two fractions together (whatever sign they were goes out front)
EXAMPLE
2) If they are different: I can subtract those two fractions
(the sign from the bigger fraction goes out front)
EXAMPLE
