Algebra.Com's Answer #431608 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! a boy weighs 56.7kg. If he reduces his weight in the ratio 7:6, \n" ); document.write( " find his new weight. \n" ); document.write( ": \n" ); document.write( "Follow the procedure and you will see why. \n" ); document.write( ": \n" ); document.write( "Let x = the new weight. \n" ); document.write( "write it as a ratio equation \n" ); document.write( "Old weight is to new weight; \n" ); document.write( "Cross multiply \n" ); document.write( "7x = 56.7 * 6 \n" ); document.write( "7x = 340.2 \n" ); document.write( "x = \n" ); document.write( "x = 48.6 \n" ); document.write( " |
