Answer:
[tex]\frac{7}{8}[/tex] gallon.
Step-by-step explanation:
We have been given that Pheng-Xu drinks 1 cup of milk every day for lunch.
1 week = 7 days
2 weeks = 2*7 days = 14 days.
First of all, we will find number of cups needed by Pheng-Xu in two weeks by multiplying 1 by 14.
[tex]\text{Number of cups of milk needed}=1\times 14[/tex]
[tex]\text{Number of cups of milk needed}=14[/tex]
1 US fluid gallon equals 16 cups of milk.
Now, we will divide 14 by 16 to find gallons of milk needed by Pheng-Xu.
[tex]\text{Gallons of milk needed}=\frac{14}{16}[/tex]
[tex]\text{Gallons of milk needed}=\frac{2*7}{2*8}[/tex]
[tex]\text{Gallons of milk needed}=\frac{7}{8}[/tex]
Therefore, Pheng-Xu needs [tex]\frac{7}{8}[/tex] gallon of milk.
