Answer: The answer is [tex]\dfrac{2}{9}.[/tex]
Step-by-step explanation: Given in the question that Emily pours [tex]\dfrac{7}{9}[/tex] of a pint of coffee in the cup. We are to find the fraction of the milk that a customer can add to the cup.
Fraction of the pint of coffee in the cup is given by
[tex]f_c=\dfrac{7}{9}.[/tex]
The fraction of the cup that is left unfilled will be
[tex]f_u=1-\dfrac{7}{9}=\dfrac{9-7}{9}=\dfrac{2}{9}.[/tex]
Therefore, the fraction of the cup that can be filled with milk is
[tex]f_m=f_u=\dfrac{2}{9}.[/tex]
Thus, the answer is [tex]\dfrac{2}{9}.[/tex]
Answer: A customer can add 2/9 of milk to the cup.
Step-by-step explanation:
Hi, to answer this we have to subtract the amount of coffee in the cup ( 7/9 of a pint) to the total capacity of the cup (1).
Mathematically speaking
1- 7/9 = 2/9
2/9 of a cup is the capacity left for adding milk.
A customer can add 2/9 of milk to the cup.
