Explanation:
Given that
Mx Duncan used three fourth of the cup of coffee
And, she realized that she only required half of the three-fourth of coffee
We need to find out the how much of the coffee does she need
So,
![= (3)/(4) * (1)/(2) \\\\= (3)/(8)](https://img.qammunity.org/2022/formulas/mathematics/high-school/qat06sxnldb2hd3pt0flwu94avj2210zbc.png)
Hence, the coffee does she need is
![(3)/(8)](https://img.qammunity.org/2022/formulas/mathematics/middle-school/9nfm9kciek35ys1wez16w9mo9epj6wrm.png)
