What is 31/12 + 2/6?

What is 31/12 + 2/6?

This is how you add

31
12
+
2
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 2 by 2, and get 4, then we multiply 6 by 2 and get 12.

2/6 times 2

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

31
12
+
4
12

Step 2

Since our denominators match, we can add the numerators.

31 + 4 = 35

Answer:

35
12

Step 3

Now, do we need to simplify this fraction?

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 31/12 + 2/6

31
12
+
2
6
=
35
