Algebra.Com's Answer #1090 by kiru_khandelwal(79) ![]() You can put this solution on YOUR website! Percentage means per 100 \n" ); document.write( "so 5% means = 5/100 \n" ); document.write( "so 5% 0f 80 will be (5/100)*80= 400/100 = 4\r \n" ); document.write( "\n" ); document.write( "SImilarly u can find out \n" ); document.write( "for example 15% of 60 \n" ); document.write( "so 15% of 60 = (15/100) of 60 = (15/100) * 60 = 900/100 = 9\r \n" ); document.write( "\n" ); document.write( "Hope this helps....\r \n" ); document.write( "\n" ); document.write( "Now let me explain the other way round\r \n" ); document.write( "\n" ); document.write( "How much percentage of 60 is 9?\r \n" ); document.write( "\n" ); document.write( "Let 9 be x% of 60 \n" ); document.write( "=> (x/100)*60 = 9 \n" ); document.write( "=> 60x = 900 \n" ); document.write( "=> x = 900/60 = 15\r \n" ); document.write( "\n" ); document.write( "So if a person gets 9 marks out of 60....in percentage it will be (9/60)*100. \n" ); document.write( " |
