Question 1118351
<br>
If a solution using algebra is not required, you can get some good mental exercise solving the problem informally with logical analysis.<br>
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.<br>
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.<br>
John has $12 and Tom has $14.
