What is 80/2 + 4/11?

This is how to 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 80 by 11, and get 880, then we multiply 2 by 11 and get 22.

Now for the second term. You multiply 4 by 2, and get 8, then multiply 2 by 11 and get 22.

This gives us a new problem that looks like so:

Step 2

Since our denominators match, we can add the numerators.

880 + 8 = 888

That gives us an answer of

Step 3

Can this fraction be reduced?

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

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

Now, try the same number again.

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...

No good. 13 is larger than 11. So we're done reducing.

Congratulations! Here's your final answer to 80/2 + 4/11
