Algebra.Com's Answer #733649 by greenestamps(13216) You can put this solution on YOUR website! \n" ); document.write( "If a solution using algebra is not required, you can get some good mental exercise solving the problem informally with logical analysis. \n" ); document.write( "If half of John's pocket money is 3/7 of Tom's, then all of John's pocket money is 6/7 of Tom's. \n" ); document.write( "Then if Tom has $2 more than John, you are looking for a fraction that is equivalent to 6/7 in which the denominator is 2 more than the numerator. Since in the fraction 6/7 the denominator is 1 more than the numerator, simply double the numerator and denominator of the fraction: 6/7 = (6*2)/(7*2) = 12/14. \n" ); document.write( "John has $12 and Tom has $14. \n" ); document.write( " |
