Stan owns 4/5 of an acre. Of that, 2/3 of the land is fenced. How many acres of land is fenced?

To find out how many acres of land are fenced, you need to multiply the total land owned by Stan by the fraction that is fenced.

First, find out how many acres Stan owns:
4/5 acre

Next, find out what fraction of the land is fenced:
2/3 of the land

Now, multiply the total land owned by the fraction that is fenced:
4/5 acre * 2/3 = (4*2)/(5*3) = 8/15 acre

Therefore, Stan has 8/15 of an acre that is fenced.
