What is 24/26 + 6/8?

What is 24/26 + 6/8?

Let's add

24
26
+
6
8

Step 1

We can't add two fractions with different denominators (the bottom number). So you need to get a common denominator - both bottom numbers need to match. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 24 by 8, and get 192, then we multiply 26 by 8 and get 208.

24/26 times 8

Do the same for the second term. We multiply 6 by 26, and get 156, then multiply 26 by 8 and get 208.

6/8 times 26

So now our fractions look like this:

192
208
+
156
208

Step 2

Since our denominators match, we can add the numerators.

192 + 156 = 348

So the answer is:

348
208

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

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

348
208
÷ 2 =
174
104

Now, try the same number again.

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

174
104
÷ 2 =
87
52

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...

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...

Nope. Try the next prime number, 43...

Nope. Try the next prime number, 47...

Nope. Try the next prime number, 53...

No good. 53 is larger than 52. So we're done reducing.

Congratulations! Here's your final answer to 24/26 + 6/8
