What is 80/2 + 1/10?

This is how you add

Step 1

Now we need to make our denominators match.

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

Multiply 80 by 5, and get 400, then we multiply 2 by 5 and get 10.

This gives us a new problem that looks like so:

Step 2

Since our denominators match, we can add the numerators.

400 + 1 = 401

So what's the answer so far?

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...

No good. 11 is larger than 10. So we're done reducing.

There you have it! Here's the final answer to 80/2 + 1/10
