Algebra.Com's Answer #354659 by lmeeks54(111)![]() ![]() You can put this solution on YOUR website! Ask the question a different way and the solution may become obvious to you. 63 is 15% of what number is the same as asking, 63 = 15% (or better, .15) * some #. But we always solve with the unknown \"some number\" on one side of the = sign and everything else on the other. \n" ); document.write( "... \n" ); document.write( "Let x = the unknown # \n" ); document.write( "... \n" ); document.write( "63 = .15 x can be rewritten by dividing both sides by .15 \n" ); document.write( "... \n" ); document.write( "x = 63/.15 \n" ); document.write( "x = 420 is the answer. \n" ); document.write( "... \n" ); document.write( "check your work by solving for your original question: \n" ); document.write( "420 * .15 = ? \n" ); document.write( "420 * .15 = 63 checks. \n" ); document.write( "... \n" ); document.write( "cheers, \n" ); document.write( "Lee \n" ); document.write( " |
