Question 1059380
Constant Rate Rule; not yet known is the lay rate for 1 hen.  Let this rate be r.


Rate unit should be {{{EGGS/DAY}}}.  Each hen lays eggs at the same rate.


{{{system(9r*9=9,3r*3=x)}}}------system is the transcription of first sentence, and second sentence; x is the unknown number of eggs.




{{{r=9/(9*9)}}}
{{{r=1/9}}}
-
{{{x=3r*3}}}
{{{x=3(1/9)*3}}}
{{{x=(3*3)/9}}}
{{{x=1}}}--------------That's all.  Just one single egg.



If this were practical, some averaging would need to be happening.
