Algebra.Com's Answer #315903 by JimboP1977(311) You can put this solution on YOUR website! let x be the number.\r \n" ); document.write( "\n" ); document.write( "To find 37 per cent of the number we need to divide by 100 and then times by 37.\r \n" ); document.write( "\n" ); document.write( "(x/100)*37 = 28 \r \n" ); document.write( "\n" ); document.write( "We need to rearrange to find x. Firstly we need to divide both sides by 37.\r \n" ); document.write( "\n" ); document.write( "(x/100) = 28/37 \r \n" ); document.write( "\n" ); document.write( "Then we need to times both sides by 100.\r \n" ); document.write( "\n" ); document.write( "x = 2800/37\r \n" ); document.write( "\n" ); document.write( "x = 75.676 (to 3 decimal places)\r \n" ); document.write( "\n" ); document.write( "Therefore the answer is C.\r \n" ); document.write( "\n" ); document.write( "Does that make any sense?
