Sam the barbarian had 11 axes. He wanted to share his axes with his 3 sons. The eldest son, Ron, can take half of the axes, while his younger son, John, can take one third of the axes. His youngest son, however, is only entitled to 1/12 of all the axes. How many axes will each of them receive? (No fractions)

Sam wasn't very good at maths, 1/2 + 1/3 + 1/12 is only 11/12, not 1.

 

However, add a dummy ax, so there are 12 axes and apply Sam's fractions to them.  Ron gets 12/2 = 6 axes; John gets 12/3 = 4 axes; the youngest gets 12/12 = 1 axe.

 

6 + 4 + 1 = 11, so this uses all Sam's axes and you can keep your own dummy axe!

first add an extra axe

here are 12 axes and apply Sam's fractions to them.  Ron gets 12/2 = 6 axes; John gets 12/3 = 4 axes; the youngest gets 12/12 = 1 ax.

 

6 + 4 + 1 = 11, so this uses all Sam's axes and you can keep your own extra axe!
