Question

A recipe for beef stew calls for 1 pound of beef and 3 potatoes. The recipe is doubled to include 2 pounds of beef and 6 potatoes. Which proportion represents the situation?

Answer 1

D. 1/3 = 2/6. Hope this helps!

Answer 2

The proportion that represents the situation is:

1 pound of beef 2 pounds of beef
---------------------- = --------------------------
3 potatoes 6 potates

As you see, when you double thre recipe you multiply both numerator and denominator by 2: 1 pound of beef * 2 = 2 pounds of beef, 3 potatoes * 2 = 6 potatoes.

Of course, the fraction 1/3 is equivalent to the fraction 2/6.
