## Step 1

Can you add yet? Nope! The platform don"t match. We require a typical denominator. So next we take both denominators and also multiply them. Next, take each numerator and also multiply the by the denominator the the various other term.

You are watching: 1�5 1�8

So, we multiply 1 by 8, and also get 8, then we multiply 5 through 8 and also get 40.

Now because that the 2nd term. You main point 1 by 5, and also get 5, climate multiply 5 by 8 and also get 40.

We now have actually a brand-new problem, that looks favor this:

8
 40
+5
40

## Step 2

Since our platform match, we can include the numerators.

8 + 5 = 13

That gives us the sum, which is

13
 40

## Step 3

Now, do we must simplify this fraction?

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

Nope! So currently we shot the next best prime number, 3...

Nope! So currently we try the next greatest prime number, 5...

Nope! So currently we shot the next biggest prime number, 7...

Nope! So now we shot the next best prime number, 11...

Nope! So currently we try the next greatest prime number, 13...

Nope! So now we try the next greatest prime number, 17...

No good. 17 is larger than 13. So we"re done reducing.

There you have it! Here"s the final answer come 1/5 + 1/81
