What is 91/1 + 8/12?

Here's how to add

Step 1

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

Since 1 is evenly divided by 12, we can multiply just one term to get a common denominator.

Multiply 91 by 12, and get 1092, then we multiply 1 by 12 and get 12.

So now our fractions look like this:

Step 2

Since our denominators match, we can add the numerators.

1092 + 8 = 1100

So the answer is:

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:

Now, try the same number again.

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

Now, try the same number again.

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

Nope. Try the next prime number, 5...

No good. 5 is larger than 3. So we're done reducing.

Congratulations! Here's your final answer to 91/1 + 8/12
