What is 22/22 + 3/10?

What is 22/22 + 3/10?

Let's add

22
22
+
3
10

Step 1

We still have different denominators (bottom numbers), though, so we need to get a common denominator. This will make the bottom numbers match. Multiply the denominators together first. Now, multiply each numerator by the other term's denominator.

Now we multiply 22 by 10, and get 220, then we multiply 22 by 10 and get 220.

22/22 times 10

Now for the second term. You multiply 3 by 22, and get 66, then multiply 22 by 10 and get 220.

3/10 times 22

This gives us a new problem that looks like so:

220
220
+
66
220

Step 2

Since our denominators match, we can add the numerators.

220 + 66 = 286

That gives us an answer of

286
220

Step 3

Can this fraction be reduced?

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

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

286
220
÷ 2 =
143
110

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...

Are both the numerator and the denominator evenly divisible by 11? Yes! So we reduce it:

143
110
÷ 11 =
13
10

Let's try dividing by that again...

No good. 11 is larger than 10. So we're done reducing.

There you have it! Here's the final answer to 22/22 + 3/10

22
