You can put this solution on YOUR website!
You could solve by proportion.
\n" ); document.write( "\"+x%2F150+=+75%2F100\"
\n" ); document.write( "Cross products gives us \"x%2A100+=+150%2A75\"
\n" ); document.write( "100x = 11250
\n" ); document.write( " x = 112.50
\n" ); document.write( "Here we have solved for the number that we need right,
\n" ); document.write( "so the number we can miss is 150 - 112.50 = 37.50 .
\n" ); document.write( "
\n" );
