Answer:
Out of given word problem , (B) word problem matches the given problem.
B) Mark drinks
of a gallon of milk every week. How much does he drink in 7 weeks? written as,
![x=\frac{2}{3}\times 7](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B2%7D%7B3%7D%5Ctimes%207)
Step-by-step explanation:
Given problem ![\frac{2}{3} \times 7](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%20%5Ctimes%207)
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
of a gallon. How much milk is left?
Mathematically represented as,
Let left milk be x then ,
![x=7-\frac{2}{3}](https://tex.z-dn.net/?f=x%3D7-%5Cfrac%7B2%7D%7B3%7D)
B)Mark drinks
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](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B2%7D%7B3%7D%5Ctimes%207)
C) Mark has
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](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B2%7D%7B3%7D%2B%207)
D) Mark has
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](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B2%7D%7B3%7D%20%5Cdiv%207)
Thus, out of given word problem , (B) word problem matches the given problem
