Ethan sold 2/3 gallon of lemonade. Kayla sold some lemonade too. Together, they sold 1 1/4 gallons. Who sold more lemonade, Ethan or Kayla? How much more ?

Rewrite 1 1/4 as an improper fraction:

1 1/4 = 5/4 gallons.

Rewrite both fractions with a common denominator:

2/3 = 8/12

5/4 = 15/12

Subtract the amount Ethan sold from total:

15/12 - 8/12 = 7/12

Kayla sold 7/12

This means Ethan sold more, because 8/12 is more than 7/12
