What is 91/1 + 1/12?

What is 91/1 + 1/12?

Here's how to add

91
1
+
1
12

Step 1

Now we need to make our denominators match.

12 goes into 1 evenly, so we only need to multiply one term to get a common denominator.

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

91/1 times 12

This gives us a new problem that looks like so:

1092
12
+
1
12

Step 2

Since our denominators match, we can add the numerators.

1092 + 1 = 1093

That gives us an answer of

1093
12

Step 3

Can this fraction be reduced?

First, we attempt to divide it by 2...

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

Nope! So now we try the next greatest prime number, 11...

Nope! So now we try the next greatest prime number, 13...

No good. 13 is larger than 12. So we're done reducing.

There you have it! Here's the final answer to 91/1 + 1/12

91

1093
