What is 3/24 + 8/11?

What is 3/24 + 8/11?

Here's how we add

3
24
+
8
11

Step 1

Of course, you can't add two fractions if the denominators (bottom numbers) don't match. To get a common denominator, multiply the denominators together. Then we fix the numerators by multiplying each one by their other term's denominator.

Now you multiply 3 by 11, and get 33, then we multiply 24 by 11 and get 264.

3/24 times 11

Do the same for the second term. We multiply 8 by 24, and get 192, then multiply 24 by 11 and get 264.

8/11 times 24

The problem now has new fractions to add:

33
264
+
192
264

Step 2

Since our denominators match, we can add the numerators.

33 + 192 = 225

The sum we get is

225
264

Step 3

The last step is to reduce the fraction if we can.

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

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

Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:

225
264
÷ 3 =
75
88

Now, try the same number again.

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...

Nope. Try the next prime number, 59...

Nope. Try the next prime number, 61...

Nope. Try the next prime number, 67...

Nope. Try the next prime number, 71...

Nope. Try the next prime number, 73...

Nope. Try the next prime number, 79...

No good. 79 is larger than 75. So we're done reducing.

Congratulations! Here's your final answer to 3/24 + 8/11
