What is 91/1 + 1/2?

What is 91/1 + 1/2?

Here's how we add

91
1
+
1
2

Step 1

We have to make sure the denominators are equal.

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

Multiply 91 by 2, and get 182, then we multiply 1 by 2 and get 2.

91/1 times 2

We now have a new problem, that looks like this:

182
2
+
1
2

Step 2

Since our denominators match, we can add the numerators.

182 + 1 = 183

That gives us the sum, which is

183
2

Step 3

Now, do we need to simplify this fraction?

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

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

No good. 3 is larger than 2. So we're done reducing.

And we're done! Here's the final answer to 91/1 + 1/2

91
1
+
1
2
=
183
2
