7friends picked 7 quarts of blueberries. three of the friends will share 4 quarts of blueberries equally and the other 4 friends will share 3 quarts of the blueberries equally. in which group does each friend get a greater amount of blueberries? explain your reasoning.

We wish to find the number of quarts per person, which we realize will be a fractional amount.  In the first instance, the fraction is 4/3, or 1 1/3 quart per person.  The second group is 3/4, or 0.75 quarts per person.  This is less.

An even easier explanation is that 3 friends splitting 4 quarts means each gets a quart of their own, plus a third of the remaining quart.  Four friends divvying up three quarts can't even make a whole quart for each.  The three have to put a quarter of the quart into a container for the fourth to enjoy equal shares.
