In  Math problems written in  English,  they  NEVER  say   " . . . three times less than . . . "

They  ALWAYS  use another form/forms.


The form  " . . . three times less than . . . "  is considered as defective,  when they formulate  Math problems in  English.


        ( In distinction from many other languages,
        where this form is considered as NORMAL
        and does not create any trouble/misunderstanding ).

Here is the grammatically correct interpretation of the nonsensical statement "the width of a rectangle is three times less than two thirds of its length".

Let x be the length; then "three times less than two thirds of its length" means "two thirds of x, minus 3 times x":

%282%2F3%29x-%283%29x+=+%28-8%2F3%29x

Assuming the length x is a positive number, we now have a width that is a negative number. Obviously that is nonsense.

Unfortunately, similar phrases are used frequently:
"Our product costs five times less to use than our competitor's product"
"The number of items in stock is three times less than it was a week ago"

One can only guess what the true numbers are, because the phrases do not make any sense.
