Add these two fractions, after converting them to their LCD: 13/18 + 8/27?\r \n" ); document.write( "\n" ); document.write( "I got the 13/18 but I can get the 8/27 I just don't get it. Thank you for your help in advance. \n" ); document.write( "------------- \n" ); document.write( "I don't know what \"I got the 13/18 \" means ?? \n" ); document.write( "------------- \n" ); document.write( "13/18 + 8/27 \n" ); document.write( "A common denominator is always the product = 27*18 = 486 \n" ); document.write( "13/18 + 8/27 = 351/486 + 144/486 = 495/486 \n" ); document.write( "= 55/54 \n" ); document.write( "----------- \n" ); document.write( "Using the LCD, 54: \n" ); document.write( "13/18 + 8/27 = 39/54 + 16/54 = 55/54 same answer. \n" ); document.write( "Don't waste time on a test finding the LCD, any common denominator works. \n" ); document.write( " \n" ); document.write( " |
