What is 3/24 + 10/12?

What is 3/24 + 10/12?

Here's how to add

3
24
 +
10
12

Step 1

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

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

Multiply 10 by 2, and get 20, then we multiply 12 by 2 and get 24.

10/12 times 2

This gives us a new problem that looks like so:

3
24
 +
20
24

Step 2

Since our denominators match, we can add the numerators.

3 + 20 = 23

That gives us an answer of

23
24

Step 3

Can this fraction be reduced?

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...

No good. 29 is larger than 23. So we're done reducing.

Congratulations! Here's your final answer to 3/24 + 10/12
