    Answer:

    5 steps

    Step-by-step explanation:

    65cm \times 8 = 520cm

    4dm = 40cm \\ 65 - 40 = 25

    25 \times 8 = 200cm \: gap

    200 \div 40 = 5

    Answer:

    His daughter has walked 13 steps

    Step-by-step explanation:

    Unit Conversion

    Each step of the father is 65 cm long and each step of his daughter is 4 dm long.

    Recalling that 1 dm = 10 cm, then each step of the daughter is 4*10 = 40 cm long.

    Now we can compare both measures. When the father has walked 8 steps, this distance is 8*65 = 520 cm, and the daughter has walked 520/40 = 13 steps.

    His daughter has walked 13 steps
