Explanation:

Given: Jessie said the rate
`\frac12` pound /
`\frac14` quart can be written as the unit rate
`\frac18` pound per quart.

The rate
`\frac12` pound /
`\frac14` quart =
`((1)/(2))/(\frac14) =\frac12*\frac41=2\ \ \ \ \ \ [ \ ((a)/(b))/((c)/(d))=(a)/(b)*(d)/(c)\ ]`

The correct unit rate = 2 pound per quart.

Her error instead dividing of that she multiplied both fraction.
