14 - How Many Heaps?
A farmer is moving manure from his shed to his fields by tractor.
After working all day, he has made 4 heaps in his barley field and 3 in his wheat field.
There is so much left in his shed that he moves the same amount into each field the next day.
If he moves all the heaps from both fields together into a third field, how many piles of manure will he have?
