Story problems that models 3 divided by 4

Partitive (equal share):
There are 3 brownies and 4 children. If each child gets an equal amount of the brownies, how much does each get?

Repeated subtraction:
Asks how much of 4 is in 3.
I have 3 carrots, but I need to put 4 carrots into each bunch to sell them at the farmer’s market. How much of a bunch do I have?

Obviously, the equal share model is much easier to use when the numerator is smaller than the denominator.
