20 of them.
Well, isn't that a happy little math problem we have here? To find out how many thirds are in six fifths, we first need to see how many thirds make up one whole. Since three thirds make a whole, we can divide six by three to find that there are two thirds in each fifth. So in six fifths, there are twelve thirds. Just like painting a beautiful landscape, sometimes all we need is a little perspective to see the whole picture.
If there are three thirds in one, there must be six thirds in two.

Two-thirds of six is not nine. Rather, two-thirds of six is four. You can find this by realizing that two-thirds of six is the same as six-thirds of two. This equates to two times two, which is four.

There are 18.
Thankfully, 3 and 9 are related! Three times three equalsnine, so three times two (of those thirds) would equal six! Six ninths are equal to two thirds.
Three thirds make up a whole.
