Question 1110302
--------------------------------------------------------------------------
three homework tasks to do. For each homework task there are theee sections. In each of these sections are three questions. 
Model this problem to work out how many questions John has to answer. 
--------------------------------------------------------------------------


RATIOS!  Use the described ratios as conversion factors (taking the form of a "fraction").  ONLY THREE STEPS NEEDED.


{{{3*homeworks*3(sections/homeworks)*3(questions/section)}}}


{{{3*3*3*questions}}}


{{{highlight(27*questions)}}}


You can also solve this problem using individual proportions; TWO of them.  Most people would not want to do it that way, but instead use the ratios as conversion factors and make one setup and work through it.
