What is 34/3 + 6/12?

What is 34/3 + 6/12?

This is how to add

34
3
+
6
12

Step 1

Our denominators (bottom numbers) don't match, so we can't add yet.

12 goes into 3 evenly, so we only need to multiply one term to get a common denominator.

Multiply 34 by 4, and get 136, then we multiply 3 by 4 and get 12.

34/3 times 4

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

136
12
+
6
12

Step 2

Since our denominators match, we can add the numerators.

136 + 6 = 142

That gives us the sum, which is

142
12

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:

142
12
÷ 2 =
71
6

Now, try the same number again.

Nope. Try the next prime number, 3...

Nope. Try the next prime number, 5...

Nope. Try the next prime number, 7...

No good. 7 is larger than 6. So we're done reducing.

Congratulations! Here's your final answer to 34/3 + 6/12

34
3
+
6
12
=
71
6
