Question

does 6.3 = 0.063 and which one is has more value.

Answer 1

Whenever you multiply number by another number smaller than 1 (but greater than 0), result will be smaller than original number.

For example: 1 × 0.99 = 0.99 (see, 0.99 is smaller than 1)

So to answer your comment on your question, it's C.
