To find that fraction, simply multiply numerator and denominator of 2/3 by 8 to get the fraction 16/24. \n" ); document.write( "That fraction 16/24 is the fraction we need to have after subtracting 5 from both numerator and denominator of the original fraction, so the original fraction is (16+5)/(24+5) = 21/29. \n" ); document.write( "ANSWER: 21/29 \n" ); document.write( " \n" ); document.write( " |
