What is 12/1 + 1/5?

What is 12/1 + 1/5?

Here's how you add

12
1
+
1
5

Step 1

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

5 goes into 1 evenly, so we only need to multiply one term to get a common denominator.

Multiply 12 by 5, and get 60, then we multiply 1 by 5 and get 5.

12/1 times 5

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

60
5
+
1
5

Step 2

Since our denominators match, we can add the numerators.

60 + 1 = 61

Answer:

61
5

Step 3

Now, do we need to simplify this fraction?

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

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

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

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

No good. 7 is larger than 5. So we're done reducing.

Congratulations! Here's your final answer to 12/1 + 1/5

12

=
61
