What is 12/1 + 6/8?

What is 12/1 + 6/8?

This is how to add

12
1
+
6
8

Step 1

Now we need to make our denominators match.

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

Multiply 12 by 8, and get 96, then we multiply 1 by 8 and get 8.

12/1 times 8

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

96
8
+
6
8

Step 2

Since our denominators match, we can add the numerators.

96 + 6 = 102

Answer:

102
8

Step 3

Now, do we need to simplify this fraction?

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

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

102
8
÷ 2 =
51
4

Let's try dividing by that again...

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

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

No good. 5 is larger than 4. So we're done reducing.

There you have it! Here's the final answer to 12/1 + 6/8

12
1
+
6
8
=
51
