No, it can be greater than 4.
The only generalisation posible is that it will always be a rational number. The product can be positive or negative; it can be a fraction or an integer, it can be larger or smaller.
No, and it is not always less than 4, either.

No. The product of a mixed number between 4 and 5 and a fraction between 0 and 1 is always less than 5, but is not always less than 4.

The only thing that you can be certain of is that the answer will be a number. It could be irrational or rational, it could be a proper fraction, integer or improper (mixed) fraction.
... always equivalent to the fraction the certain number/64,and to the product (0.015625 x the certain number).
A fraction multiplied by its reciprocal is always equal to one. This is because the reciprocal is an inversion of the fraction. The denominator of a fraction is the same number as the numerator of the reciprocal, and vice versa. The product of this is a fraction with the same numbers for the denominator and reciprocal, which is also known as an equivalent fraction. Equivalent fractions are always equal to one.
No. It can be a number between two positive integers.
