Answer:
Find the least common factor.
Step-by-step explanation:
For example, you need to add 4/5 and 4/6.
5 = 1, 5, 10, 15, 20, 25, 30.
6 = 1, 6, 12, 18, 24, 30.
The least common factor is 30.
Now, multiply 5 to get 30, and 6 to get 30. There will be a common denominator.
5 x 6 = 30
6 x 5 = 30
4/5 x 6/6 = 24/30
4/6 x 5/5 = 20/30
Now, just add.
24 + 20 = 44.
The answer is 44/30.
