What is 91/1 + 1/4?

What is 91/1 + 1/4?

This is how to add

91
1
+
1
4

Step 1

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

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

Multiply 91 by 4, and get 364, then we multiply 1 by 4 and get 4.

91/1 times 4

This gives us a new problem that looks like so:

364
4
+
1
4

Step 2

Since our denominators match, we can add the numerators.

364 + 1 = 365

That gives us an answer of

365
4

Step 3

Can this fraction be reduced?

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

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

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

No good. 5 is larger than 4. So we're done reducing.

Congratulations! Here's your final answer to 91/1 + 1/4
