What is 12/1 + 9/11?

Here's how you add

Step 1

Now we need to make our denominators match.

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

Multiply 12 by 11, and get 132, then we multiply 1 by 11 and get 11.

This gives us a new problem that looks like so:

Step 2

Since our denominators match, we can add the numerators.

132 + 9 = 141

That gives us an answer of

Step 3

Can this fraction be reduced?

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

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

Nope! So now we try the next greatest prime number, 11...

Nope! So now we try the next greatest prime number, 13...

No good. 13 is larger than 11. So we're done reducing.

There you have it! Here's the final answer to 12/1 + 9/11
