Question 1144111
.
<pre>

To solve this problem (and many other similar problems, too), you do not need to know anything.


You need two things:



    a)  to read the condition attentively; to understand every word and to understand the meaning of the problem in whole

        (usually, to get it, it is enough to read the problem  two (2)  or 3 (three) times);


    b)  a bit of common sense, that practically any human creation has to his (or her)  7 - 8  years.



In this problem, you are given a total amount of 500 pounds, and it is divided into 10 equal parts.


They ask you to evaluate the amount of each part in pounds.

At this point, a good style teaching requires me to stop.
