Answer:
Ethan sold 1/12 gallon more lemonade
Step-by-step explanation:
1 1/4 = 2/3 + x
x is the amount of lemonade Kayla sold
find least common denominator
1 3/12 = 8/12 + x
subtract 8/12 on both sides
15/12 - 8/12 = x
7/12 = x
7/12 = amount of lemonade Kayla sold
2/3 - 7/12 = how much more Ethan sold
8/12 - 7/12 = 1/12 gallon
