Write 0.00605 in scientific notation.

a) 6.05 x 10^-3
b) 6.05 x 10^-4
c) 6.05 x 10^-2
d) 6.05 x 10^-5

How many jumps is it from the decimal point to the position to the right of the 6

The answer to that is 3 jumps.  Since the move of the decimal made the number larger than it really is, it will take a negative value to put it back where it belongs.

So A) is the correct answer.  It is in scientific notation and if you move the decimal back 3 place you get the number you stared with.

That they are numbers and related to each other.

Two because two of one thing is two.
