Using these measurements, how do I convert them to the standard 5x7 card? I know

Use a proportion as follows:
\n" ); document.write( "Regarding the 5/16---------------
\n" ); document.write( "(5/16)/(9/8) = x/5
\n" ); document.write( "(5/16)/(18/16) = x/5
\n" ); document.write( "5/18 = x/5
\n" ); document.write( "x = 25/18 = 1.3888888...
\n" ); document.write( "So the 5/16 becomes 1.3888 from the top of the actual picture.
\n" ); document.write( "------------------
\n" ); document.write( "Regarding the 7/16--------------
\n" ); document.write( "(7/16)/(9/8) = x/5
\n" ); document.write( "(7/16)/(18/16) = x/5
\n" ); document.write( "(7/18) = x/5
\n" ); document.write( "x = 35/18
\n" ); document.write( "x = 1.944444....
\n" ); document.write( "So the 7/16 becomes 1.944444.. from the bottom of the actual picture.
\n" ); document.write( "======================
