Question 143682
Remember that {{{a/b=c/d}}} means that {{{ad=bc}}}.


Likewise, {{{9/6=x/8 }}} means that {{{9*8= 6*x}}}

{{{72=6x}}}


Divide both sides by 6:  {{{72/6=(6x)/6}}}
{{{12=x}}}


You can generalize this to say {{{x/b=y/(cents)}}}, and solve for "cents."  Does this make "cents" to you ???  


{{{x/b= y/(cents) }}} means that {{{x*(cents) = yb}}}


Solve for "cents":   {{{ cents = (yb)/x}}}


If you need additional help with this, see my website by clicking on my tutor name "rapaljer" anywhere in algebra.com.  Take the second link on the homepage which is "Basic, Intermediate, and College Algebra: One Step at a Time."  Click on Basic Algebra, look for Chapter 3, "Section 3.08 Ratio and Proportion."  If you hurry, you can buy this whole book (or Intermediate or College Algebra: One Step at a Time) for an introductory special $30 on Ebay by doing a search for "Rapalje".  It's a truly user-friendly explanation, unlike traditional textbooks written by mathematicians for fellow-mathematicians!!
