Question

a healthy diet follows the ratio for meat to vegetables of 2.5 servings to 4 servings. If you eat 7 servings of meat a week, how many servings of vegetables should you eat?

Answer 1

Data:

Ratio

`(meat)/(vegetables) = (2.5)/(4) = (7)/(y)`

Solving: Rule of three (directly proportional)

`(2.5)/(4) = (7)/(y)`
multiply cross

`2.5*y = 4*7`

`2.5y = 28`

`y = (28)/(2.5)`

`\boxed{\boxed{y = 11.2}}\end{array}}\qquad\quad\checkmark`

Answer:
One should eat 11.2 servings of vegetables
