    answer-

    The relative atomic mass = 204.4

    explanation:

    Thallium - 203 = 30%

    Thallium - 205 = 70%

    Therefore,

    relative mass of thallium = (30*203 + 70*205) / 100

    relative mass of thallium = (20440) / 100

    relative mass of thallium = 204.40 amu

    Thus,

    relative atomic mass of thalium = 204.4 (to 1 decimal place)
