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?
Answered by Ms. Sue
If each lot is less than one acre, then the developer must have more than 20 lots.

Please try again.

How would you work the problem? I tried dividing and multypling and it gives the same answer?
Answered by Ms. Sue
20 divided by 4/5 = 20 * 5/4 = 100/4 = 25

Answered by Rmz
Ok, but isnt 20 divided by 4/5 equal to 25 and therefore 25*5/4= 31 1/4
Answered by 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!

Answered by Rmz
So it is 25 lots not 31 1/4?
