Answer:

The correct result is 2 pounds per quart

Explanation:

Dividing Fractions

The division of two fractions \frac{a}{b} and \frac{c}{d} is written as:


\displaystyle ((a)/(b))/( (c)/(d))

This division is usually easier done by multiplying the numerator by the reciprocal of the denominator:


\displaystyle ((a)/(b))/( (c)/(d))=(a)/(b)\cdot (c)/(d)

Jessie was dividing these two fractions:


\displaystyle ((1)/(4)\ pounds)/( (1)/(8)\ quart)

And got the incorrect result


\displaystyle (1)/(32)\ \text{ pound per quart}

This mistake was probably the result of multiplying both fractions instead of dividing them.

The correct operation is:


\displaystyle ((1)/(4))/( (1)/(8))=(1)/(4)\cdot (8)/(1)=(8)/(4)=2

The correct result is 2 pounds per quart
