What is 91/1 + 3/9?

This is how to add

Step 1

We have to make sure the denominators are equal.

Since 1 is evenly divided by 9, we can multiply just one term to get a common denominator.

Multiply 91 by 9, and get 819, then we multiply 1 by 9 and get 9.

So now our fractions look like this:

Step 2

Since our denominators match, we can add the numerators.

819 + 3 = 822

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...

No good. So next you try the next prime number, which is 3...

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

So far so good... let's try to divide by that number again.

No good. So next you try the next prime number, which is 5...

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

And we're done! Here's the final answer to 91/1 + 3/9
