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

Answer:
0.000063
Step-by-step explanation:
Number of Respondents, n=1400
Probability that they would rate their financial shape as excellent = 0.09
Number of Those who would rate their financial shape as excellent
=0.09 X 1400
=126
Therefore:
The probability that 4 people chosen at random would rate their financial shape as excellent
