What is 99/7 + 1/2?

Here's how we add

Step 1

We still have different denominators (bottom numbers), though, so we need to get a common denominator. This will make the bottom numbers match. Multiply the denominators together first. Now, multiply each numerator by the other term's denominator.

Now we multiply 99 by 2, and get 198, then we multiply 7 by 2 and get 14.

Now for the second term. You multiply 1 by 7, and get 7, then multiply 7 by 2 and get 14.

This gives us a new problem that looks like so:

Step 2

Since our denominators match, we can add the numerators.

198 + 7 = 205

So what's the answer so far?

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...

Nope. Try the next prime number, 7...

Nope. Try the next prime number, 11...

Nope. Try the next prime number, 13...

Nope. Try the next prime number, 17...

No good. 17 is larger than 14. So we're done reducing.

Congratulations! Here's your final answer to 99/7 + 1/2
