    Answer:

    He spent \frac{23}{40} of his allowance

    Step-by-step explanation:

    The fraction Ebenezer spent on allowance is on Saturday is \frac{3}{8}

    The fraction he spent on Sunday is \frac{1}{5}

    The fraction of his allowance he spent is the fraction he spent on Saturday plus the fraction he spent on Sunday.

    =\frac{3}{8}+\frac{1}{5}

    The LCD is

    =\frac{3\times 5+8\times1}{40}

    =\frac{15+8}{40}

    =\frac{23}{40}
