Answer:
Out of given word problem , (B) word problem matches the given problem.
B) Mark drinks [tex]\frac{2}{3}[/tex] of a gallon of milk every week. How much does he drink in 7 weeks? written as,
[tex]x=\frac{2}{3}\times 7[/tex]
Step-by-step explanation:
Given problem [tex]\frac{2}{3} \times 7[/tex]
We are given four options and we have to chose the correct one.
We will convert each given statement into mathematical problem.
Consider,
A)Mark has 7 gallons of milk. Ernesto drinks [tex]\frac{2}{3}[/tex] of a gallon. How much milk is left?
Mathematically represented as,
Let left milk be x then ,
[tex]x=7-\frac{2}{3}[/tex]
B)Mark drinks [tex]\frac{2}{3}[/tex] of a gallon of milk every week. How much does he drink in 7 weeks?
Mathematically represented as,
Let milk drink by Mark in 7 weeks be x gallons then ,
[tex]x=\frac{2}{3}\times 7[/tex]
C) Mark has [tex]\frac{2}{3}[/tex] of a gallon of milk. Ernesto has 7 gallons of milk. How much do they have together?
Mathematically represented as,
Let they together they drink x gallon milk, then
[tex]x=\frac{2}{3}+ 7[/tex]
D) Mark has [tex]\frac{2}{3}[/tex] of a gallon of milk to divide among 7 family members. How much milk does each person get?
Mathematically represented as,
Let each person gets x gallon milk, then
[tex]x=\frac{2}{3} \div 7[/tex]
Thus, out of given word problem , (B) word problem matches the given problem
