What is 1/11 + 3/4?

What is 1/11 + 3/4?

Here's how you add

1
11
+
3
4

Step 1

Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term.

So, we multiply 1 by 4, and get 4, then we multiply 11 by 4 and get 44.

1/11 times 4

Now for the second term. You multiply 3 by 11, and get 33, then multiply 11 by 4 and get 44.

3/4 times 11

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

4
44
+
33
44

Step 2

Since our denominators match, we can add the numerators.

4 + 33 = 37

Answer:

37
44

Step 3

Now, do we need to simplify this fraction?

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

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

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

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

Nope. Try the next prime number, 11...

Nope. Try the next prime number, 13...

Nope. Try the next prime number, 17...

Nope. Try the next prime number, 19...

Nope. Try the next prime number, 23...

Nope. Try the next prime number, 29...

Nope. Try the next prime number, 31...

Nope. Try the next prime number, 37...

Nope. Try the next prime number, 41...

No good. 41 is larger than 37. So we're done reducing.

Congratulations! Here's your final answer to 1/11 + 3/4
