Answer:
the coffee does she need is [tex]\frac{3}{8}[/tex]
Step-by-step 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,
[tex]= \frac{3}{4} \times \frac{1}{2} \\\\= \frac{3}{8}[/tex]
Hence, the coffee does she need is [tex]\frac{3}{8}[/tex]
