Step-by-step explanation:
When factoring an expression like this, you need to divide all of the parts by a common number or variable. In this case, the only thing all of these numbers share is that they are divisible by 648. So, you would divide each number by 648 to simplify it, getting 1, 3, 4, and 2. Put these numbers in front of their respective variables, and put 648 outside of the parentheses to get the final answer.

Answer:
a.) Let the total number be : x
∴(73.7÷x) ×100 = 55%
∴x= (73.7×100) ÷ 55
=> 7370÷55
∴x=134
Thus, Option-A.
----------------------------------------------------
b.)  Let the percentage  be : x
∴x= (46÷65) ×100  
∴x= (0.707) × 100
∴x=70.7%
Thus, Option-B.

<h3>f(x) is equal to 4.5 when x = 1/2</h3>
<em><u>Solution:</u></em>
Given that,

We have to find f(x) when x = 1/2
We can solve by substituting x = 1/2 in given function

Thus f(x) is equal to 4.5 when x = 1/2
