If each lot is less than one acre, then the developer must have more than 20 lots.
Please try again.
A land developer wants to develop 20 acers of land. Each lot in the development is to be 4/5 of an acer. How many lots will the developer have in 20 acers?
is it 16 lots?

How would you work the problem? I tried dividing and multypling and it gives the same answer?
20 divided by 4/5 = 20 * 5/4 = 100/4 = 25
Ok, but isnt 20 divided by 4/5 equal to 25 and therefore 25*5/4= 31 1/4
Whoa -- you're making it more complicated.
The developer will have 25 lots on his 20 acres.
Let's work that backwards.
25 * 4/5 = 100/5 = 20 acres. That works!

So it is 25 lots not 31 1/4?
