What is 6/2 + 8/12?

What is 6/2 + 8/12?

Here's how to add

6
2
+
8
12

Step 1

Our denominators (bottom numbers) don't match, so we can't add yet.

Since 2 is evenly divided by 12, we can multiply just one term to get a common denominator.

Multiply 6 by 6, and get 36, then we multiply 2 by 6 and get 12.

6/2 times 6

So now our fractions look like this:

36
12
+
8
12

Step 2

Since our denominators match, we can add the numerators.

36 + 8 = 44

Now we have an answer.

44
12

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

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

44
12
÷ 2 =
22
6

Now, try the same number again.

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

22
6
÷ 2 =
11
3

Now, try the same number again.

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

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

No good. 5 is larger than 3. So we're done reducing.

Congratulations! Here's your final answer to 6/2 + 8/12

6
2
+
8
12
=
11
