Question 1142245
.
<pre>
From the condition, you have this equation


    0.35x = 12,


where "x" is the class population.


From the equation,


    x = {{{12/0.35}}} = 34.29 (approximately).


Rounding the answer to the nearest integer, you get the <U>ANSWER</U> : total number of students in the class is 34.
</pre>

--------------


In my view, the problem formulation IS NOT PERFECT.


When I read it for the first time, I may get understanding that 12 is the total number of students in the class.


Only when I read the second phrase, I start understand that it is not so.



Therefore, from my point of view, the problem, as it is presented, does not pass the test for accuracy . . . 


Math problem should be presented / formulated in a more accurate way . . .
