What is 12/1 + 6/11?

What is 12/1 + 6/11?

This is how you add

12
1
+
6
11

Step 1

Now we need to make our denominators match.

Since 1 is evenly divided by 11, we can multiply just one term to get a common denominator.

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

12/1 times 11

The problem now has new fractions to add:

132
11
+
6
11

Step 2

Since our denominators match, we can add the numerators.

132 + 6 = 138

The sum we get is

138
11

Step 3

The last step is to reduce the fraction if we can.

To find out, we try dividing 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 + 6/11

12
