 # What is 1/12 + 6/10? 1 12
+
 6 10

## Step 1

We still have different denominators (bottom numbers), though, so we need to get a common denominator. This will make the bottom numbers match. Multiply the denominators together first. Now, multiply each numerator by the other term's denominator.

Now we multiply 1 by 10, and get 10, then we multiply 12 by 10 and get 120. Now for the second term. You multiply 6 by 12, and get 72, then multiply 12 by 10 and get 120. This gives us a new problem that looks like so:

 10 120
+
 72 120

## Step 2

Since our denominators match, we can add the numerators.

10 + 72 = 82

So what's the answer so far?

 82 120

## 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:

 82 120
÷ 2 =
 41 60

So far so good... let's try to divide by that number again.

No good. So next you try the next prime number, which is 3...

No good. So next you try the next prime number, which is 5...

No good. So next you try the next prime number, which is 7...

No good. So next you try the next prime number, which is 11...

No good. So next you try the next prime number, which is 13...

No good. So next you try the next prime number, which is 17...

No good. So next you try the next prime number, which is 19...

No good. So next you try the next prime number, which is 23...

No good. So next you try the next prime number, which is 29...

No good. So next you try the next prime number, which is 31...

No good. So next you try the next prime number, which is 37...

No good. So next you try the next prime number, which is 41...

No good. So next you try the next prime number, which is 43...

No good. 43 is larger than 41. So we're done reducing.

And we're done! Here's the final answer to 1/12 + 6/10

 1 12
+
 6 10
=
 41 60
