Answer
$\frac{3}{8}$
Work Step by Step
We can write the given ratio as a fraction and then simplify in lowest terms.
We know that there are 2 pints in 1 quart, so we can write 4 quarts as $(4\times2)=8$ pints.
$\frac{3pints}{8pints}$
Since both the denominator and numerator have the same unit, we can divide out the common unit.
$\frac{3}{8}$
This fraction cannot be simplified, so the ratio is in simplest terms.
