Answer:
Example: 2/3 + 4/6 + 5/12
Explanation:
First find the least common multiple.
2*
2, 4, 6,8, 10. 12, 14, 16, 18, 20
6*
6, 12, 18, 24, 30, 36, 42, 48
12*
12, 24, 36, 48, 60, 74
the least common multiple all three denominators share is -12-
*Evaluate*
2/3 = 8/12
2 times 4 is 8
3 times 4 is 12
*whatever you do to the top you do to the bottom*
