Step 1 : Let's review the information given to us to answer the exercise correctly.
Amount of lemonade Greg made = 2/3 of a gallon
Number of friends = 4
Step 2: Let's calculate the amount of lemonade that each friend will get, using the Direct Rule of Three, as follows:
Lemonade (gallon) Friends
2/3 4
x 1
________________________________
4* x = 2/3 * 1
4x = 2/3
Dividng by 4 at both sides:
4x/4 = (2/3) / 4
x = 2/3 * 1/4
x = 2/12
x = 1/6 (Simplifying)
Step 3: Each friend will get 1/6 of a gallon of lemonade
