4 3/8 x 6 2/5\r
\n" ); document.write( "\n" ); document.write( "4 times by 8 (the denominator) and add by 3
\n" ); document.write( "6 times by 5 (the denominator) and add by 2\r
\n" ); document.write( "\n" ); document.write( "which is:
\n" ); document.write( "4x8= 24 + 3= 27/8
\n" ); document.write( "6x5= 30 + 2= 32/5\r
\n" ); document.write( "\n" ); document.write( "then find the LCM of 8 and 5= 40 (the denominator)\r
\n" ); document.write( "\n" ); document.write( "hence; 27(5)/8(5)= 135/ 40 = 3.375
\n" ); document.write( " 32(8)/5(8)= 256/ 40 = 6.4\r
\n" ); document.write( "\n" ); document.write( "therefore; 3.375 x 6.4 = 21.6
\n" ); document.write( "
