I was thinking more about how you could show students this problem. I
remembered an article in "Teaching Children Math" that used the area
model as a visual for percentage problems. I think that same idea
might work here. If we used a rectangle to represent Santa's working
life, the area of the rectangle is the whole or 100% of his working
life. Students could section off the rectangle by the various
fractions. The remaining piece is worth 13, we know this from the
problem. This will give the students a strong visual in which they
can make educated guesses as to the value of the various fractional
parts of (percentage of) Santa's working life. You could at this
point use the least common denominator as was previously suggested to
help convert from the fractions to actual years.
