Answer: a) 6000
reason:
if 7 out of 10 doctors prefer cough up syrup, then that means 4200 is 7/10ths of the doctors
divide 4200 by 7 to get 600
then, multiply 600 by 10 to get 6000, the total number of doctors
-3, 28, 500, 64, -10, -25 these al have greater absolute values than 2 1/2
We have the rational expression

; to simplify it, we are going to try to find a common factor in the numerator, and, if we are luckily, that common factor will get rid of the denominator

.
Notice that in the denominator all the numbers are divisible by two, so 2 is part of our common factor; also, all the terms have the variable

, and the least exponent of that variable is 1, so

will be the other part of our common factor. Lets put the two parts of our common factor together to get

.
Now that we have our common factor, we can rewrite our numerator as follows:

We are luckily, we have

in both numerator and denominator, so we can cancel those out:


We can conclude that the simplified version of our rational function is

.
