Algebra.Com's Answer #29204 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Here's one way to approach this problem.\r \n" ); document.write( "\n" ); document.write( "1) You can convert the given mixed numbers to improper fractions, find their common denominator, then perform the indicated operations.\r \n" ); document.write( "\n" ); document.write( "6 2/9 = 56/9 \n" ); document.write( "1 3/4 = 7/4 \n" ); document.write( "3 5/6 = 23/6\r \n" ); document.write( "\n" ); document.write( "Now you need to find the common denominator of 9, 4, and 6. \n" ); document.write( "What number will 9, 4, and 6 go into? \n" ); document.write( "Answer: 36\r \n" ); document.write( "\n" ); document.write( "Now convert the improper fractions to 36ths.\r \n" ); document.write( "\n" ); document.write( "56/9 = 224/36 (You multiplied top and bottom by 4) \n" ); document.write( "7/4 = 63/36 (You multiplied top and bottom by 9) \n" ); document.write( "23/6 = 138/36 (You multiplied top and bottom by 6)\r \n" ); document.write( "\n" ); document.write( "Now perform the indicated operations.\r \n" ); document.write( "\n" ); document.write( "224/36 + 63/36 - 138/36 = 287/36 - 138/36 = 149/36 Now simplify this.\r \n" ); document.write( "\n" ); document.write( "149/36 = 4 5/36\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
