Question 684001
For an equation, why don't you set up a ratio:


Let x = number of questions


{{{(Points)/(Questions) = (5 points)/(1 question) = (30 points)/(x questions) }}}


Now, {{{a/b=c/d}}} means that {{{ad=bc}}}.


{{{5/1=30/x}}} means that {{{5x=30}}}


Now, solve for x by dividing both sides by 5:

{{{x=6}}}
