 # What is 1/2 + 10/12? Here's how we add

 1 2
+
 10 12

## Step 1

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

12 goes into 2 evenly, so we only need to multiply one term to get a common denominator.

Multiply 1 by 6, and get 6, then we multiply 2 by 6 and get 12. This gives us a new problem that looks like so:

 6 12
+
 10 12

## Step 2

Since our denominators match, we can add the numerators.

6 + 10 = 16

That gives us an answer of

 16 12

## Step 3

Can this fraction be reduced?

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

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

 16 12
÷ 2 =
 8 6

Now, try the same number again.

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

 8 6
÷ 2 =
 4 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 4. So we're done reducing.

Congratulations! Here's your final answer to 1/2 + 10/12

 1 2
+
 10 12
=
 4 3
