    Step-by-step explanation:

    Given that,

    The mass of a patient = 70 kg

    A 70kg patient has approximately 8 pints of blood.

    The patient donates 470mL of blood.

    We know that,

    1 pint = 568 mL

    8 pints = 4544 mL

    Required fraction,

    \dfrac{470}{4544}=0.1\\\\=\dfrac{1}{10}

    So, the required fraction is approximately \dfrac{1}{10}.
