Hi,
There were 10 apples. Now there are 9. So, there's one less apple. (or "one apple less"?)
I have lots of things to do. I already went to the mall. So, I now have one less thing to do. (or "one thing less to do"?)
When I use "more", I put it between the number and the object: one more apple, two more things to do, etc.
When I want it the other way around, where is "less" usually placed?
Thanks
