The \"+90+\" fluid ounces that was added made
\n" ); document.write( "up the difference between \"+1%2F8+\" full and \"+3%2F4+\" full
\n" ); document.write( "Note that \"+3%2F4+=+6%2F8+\", and the difference \"+6%2F8+-+1%2F8+=+5%2F8+\"
\n" ); document.write( "----------------------------------------------------------
\n" ); document.write( "This is saying that \"+5%2F8+\" of the tank holds \"+90+\" fluid ounces
\n" ); document.write( "Each of these \"+5+\" 1/8's holds \"+1%2F5+\" of \"+90+\"
\n" ); document.write( "So \"+1%2F8+\" of a tank holds \"+1%2F5+\" of \"+90+\"
\n" ); document.write( "\"+8+\" times \"+1%2F8+\" is a full tank, so 1 tank contains
\n" ); document.write( "\"+%28+8%2F5+%29%2A90+\"
\n" ); document.write( "\"+%28+8%2F5+%29%2A90+=+720%2F5+\"
\n" ); document.write( "\"+720%2F5+=+144+\"
\n" ); document.write( "(a)
\n" ); document.write( "The tank holds 144 fluid ounces
\n" ); document.write( "-------------------------------
\n" ); document.write( "(b)
\n" ); document.write( "Originally there was \"+%281%2F8%29%2A144+=+18+\" fluid ounces
\n" ); document.write( "------------------------------------------------
\n" ); document.write( "(c)
\n" ); document.write( "\"+%282%2F3%29%2A144+=+96+\" fluid ounces
\n" ); document.write( "--------------------------------
