Question

Write 0.00605 in scientific notation.

Answer 1

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.
