Step 1
Of course, girlfriend can"t add two fountain if the denominators (bottom numbers) don"t match. To obtain a usual denominator, main point the denominators together. Climate we resolve the molecule by multiplying every one through their various other term"s denominator.

Now you multiply 2 by 5, and also get 10, then us multiply 3 by 5 and get 15.

Do the very same for the second term. Us multiply 4 by 3, and get 12, then multiply 3 by 5 and also get 15.

The difficulty now has new fractions to add:

15 |
Step 2
Since our platform match, us can add the numerators.
10 + 12 = 22
The sum we gain is
15 |
Step 3
The last step is to minimize the portion if we can.
To uncover out, we try dividing that by 2...
