## Step 1

We quiet have different denominators (bottom numbers), though, so we require to obtain a usual denominator. This will make the bottom numbers match. Main point the denominators together first. Now, multiply each numerator by the other term"s denominator.

You are watching: 1-5-3-7-5-9-

Now us multiply 2 by 7, and also get 14, then we multiply 9 by 7 and get 63.

Now because that the second term. You main point 3 by 9, and also get 27, then multiply 9 by 7 and also get 63.

This gives us a new problem that looks choose so:

14
 63
+27
63

## Step 2

Since our platform match, us can add the numerators.

14 + 27 = 41

So what"s the answer therefore far?

41
 63

## Step 3

Can this portion be reduced?

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

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

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

Nope! So currently we try the next greatest prime number, 7...

Nope! So currently we shot the next biggest prime number, 11...

Nope! So now we try the next best prime number, 13...

Nope! So currently we shot the next biggest prime number, 17...

Nope! So now we shot the next best prime number, 19...

Nope! So currently we shot the next best prime number, 23...

Nope! So now we shot the next best prime number, 29...

Nope! So now we try the next biggest prime number, 31...

Nope! So currently we shot the next biggest prime number, 37...

Nope! So now we try the next greatest prime number, 41...

Nope! So now we shot the next greatest prime number, 43...

No good. 43 is larger than 41. So we"re done reducing.

There you have it! Here"s the last answer to 2/9 + 3/72
 9
+3
7
=41
63
