You can put this solution on YOUR website!
(45 books)(6.3cm)=283.5 cm\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "283.5cm=(2.1cm)(x books)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x=135 books\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "another way to solve this is that we know that 6.3 is 3 times 2.1
\n" ); document.write( "so if 6.3=45 books, then multiply 45 books by 3 to get (2.1)(3)=6.3\r
\n" ); document.write( "\n" ); document.write( "45x3=135 books
\n" ); document.write( "
