  1. To find out how much lemonade Edmond used, we can start with the amount Ivan used and multiply it by the factor given in the problem.

    Ivan used ( frac{1}{2} ) cup of lemonade. According to the question, Edmond used 4 1/3 times as much lemonade as Ivan.

    First, we need to convert 4 1/3 into an improper fraction:

    [

    4 frac{1}{3} = frac{4 times 3 + 1}{3} = frac{12 + 1}{3} = frac{13}{3}

    ]

    Now, we multiply this fraction by the amount Ivan used:

    [

    text{Amount of lemonade Edmond used} = frac{13}{3} times frac{1}{2}

    ]

    To multiply these fractions, we multiply the numerators and the denominators:

    [

    frac{13 times 1}{3 times 2} = frac{13}{6}

    ]

    This fraction can be written as a mixed number as follows:

    [

    frac{13}{6} = 2 frac{1}{6}

    ]

    So, Edmond used ( frac{13}{6} ) cups of lemonade, which is also ( 2 frac{1}{6} ) cups.

    **Answer: Edmond used ( frac{13}{6} ) cups
