Question

Mandy divided a 12-pound bag of oranges into 7 equal piles. Which rational number represents the weight of each pile?

Answer 1

A proportion is a quick and easy way to say this-to-this equals that-to-that. Our "this" is 12 pounds to 7 piles, and our "that" is ? pounds to 1 pile. We can write our equation thus:

12 X

-- = -- Now cross-multiply and solve for X.

7 1

(7) (X) = (12) (1) or 7X = 12 then X = 12/7 or 1 and 5/12

OR the repeating decimal ______

1.714285

Answer 2

12/7! A rational number is a number that can be written as a fraction. So that makes 12/7 :)

Answer 3

A rational number is in the form of a ratio, a / b.

For this data 12 / 7.
