Step 1

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

You are watching: 1/5 + 1/2

Now we multiply 1 by 5, and get 5, then we multiply 2 through 5 and get 10.

*

Now for the 2nd term. You multiply 1 by 2, and get 2, climate multiply 2 by 5 and get 10.

*

This provides us a new problem that looks favor so:

5
10
+2
10

Step 2

Since our denominators match, we can add the numerators.

5 + 2 = 7

That gives us response of

7
10

Step 3

Can this fraction be reduced?

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

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

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

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

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

No good. 11 is bigger than 7. For this reason we"re done reducing.

There you have actually it! Here"s the last answer to 1/2 + 1/51
2
+1
5
=7
10
