    Answer:

    Andy’s claim is incorrect

    Step-by-step explanation:

    Given

    Mike:

    Tuesday = \frac{2}{4}

    Wednesday = \frac{1}{3}

    Andy:

    Tuesday = \frac{1}{2}

    Wednesday = \frac{1}{5}

    Required

    Is Andy correct?

    First, we need to calculate the fraction of book read by Mike.

    Mike = \frac{2}{4} + \frac{1}{3}

    Take LCM

    Mike = \frac{6+4}{12}

    Mike = \frac{10}{12}

    Convert to decimal

    Mike = 0.833\\

    Next, we perform the same calcuation for Andy

    Andy = \frac{1}{2} + \frac{1}{5}

    Take LCM

    Andy = \frac{5+2}{10}

    Andy = \frac{7}{10}

    Convert to decimal

    Andy = 0.70

    Andy’s claim that he read more of the book is incorrect because 0.833 (for Mike) is greater than 0.70 (for Andy)
