Step 1

Of course, friend can"t include two fractions if the denominators (bottom numbers) don"t match. To acquire a typical denominator, main point the platform together. Then we deal with the numerators by multiplying each one by their other term"s denominator.

You are watching: 1/4 plus 1/4

Now you multiply 1 by 5, and get 5, then us multiply 4 through 5 and also get 20.

*

Do the exact same for the 2nd term. We multiply 4 through 4, and get 16, climate multiply 4 through 5 and also get 20.

*

The problem now has brand-new fractions come add:

5
20
+16
20

Step 2

Since our platform match, we can include the numerators.

5 + 16 = 21

The sum we gain is

21
20

Step 3

The last action is to reduce the fraction if us can.

To find out, we try dividing the by 2...

No good. So next you shot the next prime number, which is 3...

No good. So next you try the next prime number, i beg your pardon is 5...

No good. So following you shot the following prime number, which is 7...

No good. So following you try the following prime number, i m sorry is 11...

No good. So following you shot the next prime number, i beg your pardon is 13...

No good. So next you try the following prime number, i beg your pardon is 17...

No good. So next you shot the next prime number, which is 19...

No good. So next you try the next prime number, which is 23...

No good. 23 is bigger than 21. So we"re excellent reducing.

And we"re done! Here"s the last answer come 1/4 + 4/51
