Algebra.Com's Answer #82006 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! You can't reduce it to 8 1/2, but you can reduce it. \n" ); document.write( ". \n" ); document.write( "You got 30/4 and that is correct. \n" ); document.write( ". \n" ); document.write( "Then you divided 4 into 30 and you got 7 2/4 and that is also correct. \n" ); document.write( ". \n" ); document.write( "Next you can recognize that 2/4 is equivalent to 1/2. [You can get that by dividing the \n" ); document.write( "numerator and the denominator of 2/4 by 2. That makes the numerator 1 and the denominator 2.] \n" ); document.write( ". \n" ); document.write( "So your answer of 7 2/4 becomes 7 1/2 when you replace the 2/4 by its equal of 1/2. \n" ); document.write( ". \n" ); document.write( "The reduced answer to this problem is 7 1/2 .... not 8 1/2. \n" ); document.write( ". \n" ); document.write( "You did everything else correctly. Good job!!! \n" ); document.write( ". \n" ); document.write( " |
