If each lot is less than one acre, then the developer must have more than 20 lots.

How would you work the problem? I tried dividing and multypling and it gives the same answer?
Ms. Sue
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
Ms. Sue
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?
