Step 1

Of course, girlfriend can"t add two fountain if the denominators (bottom numbers) don"t match. To obtain a usual denominator, main point the denominators together. Climate we resolve the molecule by multiplying every one through their various other term"s denominator.

You are watching: What is 2/3 of 4/5

Now you multiply 2 by 5, and also get 10, then us multiply 3 by 5 and get 15.

*

Do the very same for the second term. Us multiply 4 by 3, and get 12, then multiply 3 by 5 and also get 15.

*

The difficulty now has new fractions to add:

10
15
+12
15

Step 2

Since our platform match, us can add the numerators.

10 + 12 = 22

The sum we gain is

22
15

Step 3

The last step is to minimize the portion if we can.

To uncover out, we try dividing that by 2...

No good. So next you try the following prime number, i m sorry is 3...

No good. So next you shot 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 next you shot the next prime number, i m sorry is 11...

No good. So next you try the next prime number, i m sorry is 13...

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

No good. 17 is larger than 15. So we"re done reducing.

And we"re done! Here"s the last answer come 2/3 + 4/52
