4/7+1/3 = Enter your answer as a fraction in simplest form by filling in the boxes.
Evgen [1.6K]

Answer:

Step-by-step explanation:

First, you need to find the GCF of both denominators.

That would be 21.

You would need to multiple the 7 in 4/7 by 3, to get to 21. That means you would also have to multiply 3 by the 4. You should get 12/21.

Do you same thing to 1/3.

After that you should get the 2 factions, 12/21 and 7/21

12/21 + 7/21 = 19/21

There isn't anyway to simplify it, meaning the final answer is 19/21.
