What is 11/12 + 4/6?

What is 11/12 + 4/6?

Here's how you add

11
12
 +
4
6

Step 1

Now we need to make our denominators match.

12 goes into 6 evenly, so we only need to multiply one term to get a common denominator.

Multiply 4 by 2, and get 8, then we multiply 6 by 2 and get 12.

4/6 times 2

This gives us a new problem that looks like so:

11
12
 +
8
12

Step 2

Since our denominators match, we can add the numerators.

11 + 8 = 19

That gives us an answer of

19
12

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 12. So we're done reducing.

There you have it! Here's the final answer to 11/12 + 4/6
