Algebra.Com's Answer #236084 by mommasita(1)![]() ![]() ![]() You can put this solution on YOUR website! 3/5 + 1/2 + 3/4\r \n" ); document.write( "\n" ); document.write( "3/5 = 12/20 \n" ); document.write( "1/2 = 10/20 \n" ); document.write( "3/4 = 15/20\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "You have to find the common denomonator which is where 20 comes in and becomes the denomonator. Then 20 divided by 5 is 4 and 4x3=12. \n" ); document.write( "20 divided by 2 is 10 and 10x1=10. \n" ); document.write( "20 divided by 4 is 5 and 5x3=15.\r \n" ); document.write( "\n" ); document.write( "So now you can add yoru problem. \r \n" ); document.write( "\n" ); document.write( "12/20 + 10/20 + 15/20 = 37/20.\r \n" ); document.write( "\n" ); document.write( "Now you have to reduce this down as it is an improper fraction.\r \n" ); document.write( "\n" ); document.write( "Divide 37 by 20 and you get 1 with remainder of 17.\r \n" ); document.write( "\n" ); document.write( "So yoru final answer would be 1 17/20 is how long Kristi exercised. \n" ); document.write( " |
