Answer 1

5 steps

`65cm * 8 = 520cm`

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

`25 * 8 = 200cm \: gap`

`200 / 40 = 5`

Answer 2

His daughter has walked 13 steps

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
