What is 22/22 + 8/11?

What is 22/22 + 8/11?

Here's how to add

22
22
+
8
11

Step 1

Now we need to make our denominators match.

22 goes into 11 evenly, so we only need to multiply one term to get a common denominator.

Multiply 8 by 2, and get 16, then we multiply 11 by 2 and get 22.

8/11 times 2

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

22
22
+
16
22

Step 2

Since our denominators match, we can add the numerators.

22 + 16 = 38

That gives us the sum, which is

38
22

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:

38
22
÷ 2 =
19
11

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...

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 11. So we're done reducing.

There you have it! Here's the final answer to 22/22 + 8/11

22
22
+
8
11
=
19
