Help how do you do this

Firstly you'll need a calculator to solve these.
I'll use question 1 as an example
You'll divide 56 by 64
resulting in [tex] \frac{7}{8} [/tex]
you then divide 7 by 8
resulting in [tex] 0.875 [/tex] thus it's terminating as the last digit isn't repeating such as the example [tex] 0.875555555555 [/tex]
