What is 7/14 + 2/8?

This is how we add

Step 1

Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term.

So, we multiply 7 by 8, and get 56, then we multiply 14 by 8 and get 112.

Now for the second term. You multiply 2 by 14, and get 28, then multiply 14 by 8 and get 112.

We now have a new problem, that looks like this:

Step 2

Since our denominators match, we can add the numerators.

56 + 28 = 84

That gives us the sum, which is

Step 3

Now, do we need to simplify this fraction?

First, we attempt to divide it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

Now, try the same number again.

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

Now, try the same number again.

Nope. Try the next prime number, 3...

Nope. Try the next prime number, 5...

Nope. Try the next prime number, 7...

Are both the numerator and the denominator evenly divisible by 7? Yes! So we reduce it:

Now, try the same number again.

No good. 7 is larger than 3. So we're done reducing.

Congratulations! Here's your final answer to 7/14 + 2/8
