Out of given word problem , (B) word problem matches the given problem.

B) Mark drinks
`(2)/(3)` of a gallon of milk every week. How much does he drink in 7 weeks? written as,

`x=(2)/(3)* 7`

Explanation:

Given problem
`(2)/(3) * 7`

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
`(2)/(3)` of a gallon. How much milk is left?

Mathematically represented as,

Let left milk be x then ,

`x=7-(2)/(3)`

B)Mark drinks
`(2)/(3)` 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 ,

`x=(2)/(3)* 7`

C) Mark has
`(2)/(3)` 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

`x=(2)/(3)+ 7`

D) Mark has
`(2)/(3)` 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

`x=(2)/(3) / 7`

Thus, out of given word problem , (B) word problem matches the given problem
