Answer 2

Answer:

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

B) Mark drinks $\frac{2}{3}$  of a gallon of milk every week. How much does he drink in 7 weeks? written as,

$x=\frac{2}{3}\times 7$

Step-by-step explanation:

 Given problem $\frac{2}{3} \times 7$

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 $\frac{2}{3}$ of a gallon. How much milk is left?

Mathematically represented as,

Let left milk be x then ,

$x=7-\frac{2}{3}$

B)Mark drinks $\frac{2}{3}$  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 ,

$x=\frac{2}{3}\times 7$

C) Mark has $\frac{2}{3}$ 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

$x=\frac{2}{3}+ 7$

D) Mark has $\frac{2}{3}$ 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

$x=\frac{2}{3} \div 7$

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