Answer: 
Step-by-step explanation:
You need to remember the Distributive property:
And the multiplication of signs:
Therefore, applying the explained before, to simplify the expression 
you need to multiply each term that are inside of the parentheses by -2, then you get:
So, 2700/20 would be exactly 135!
-- There are an infinite number of different numbers between 2.65 and 2.66 .
To create one, just write ' 2.65 ' and add any quantity of any digits you want
after the ' 5 '.
-- If you want the number that's exactly in the middle between them, then
that's just the <em><u>average</u></em> of the two numbers.
The average of any two numbers is (1/2) x (the sum of the numbers).
(1/2) (2.65 + 2.66) = (1/2) (5.31) = <em>2.655</em> .
