Question 811226
Simple Proportion, and then find difference.  Easier way?


{{{1.5/32=v/30}}}
{{{v=1.5*30/32}}}
{{{v=1.40625}}} cups


{{{1.50000-1.40625=highlight(0.09375)}}} cups


As a practical matter, {{{0.09375*8}}} {{{cup(fluidOunce/cup)}}}
Which is {{{3/4}}} fluid ounces of sugar less for 30 people than for 32 people.
