To round the number 2.07 to seven decimal places, we look at the eighth decimal place, which is 0. Since 0 is less than 5, we do not round up. Therefore, the number remains 2.0700000 when rounded to seven decimal places.

It is 0.000033... (repeating).
that is what you just said. 0.2 two tenths, 20 hundredths, 200 thousandths. 0.2 is already in decimal form. It would be read as: two-tenths, or two-tenths (of one). Or, since it can be read as a fraction, since 0.2 is less than one, you would have 20%. Another way to understand this decimal is to convert it to it's lowest common denominator. Understanding that 0.2 = 2/10 (two-tenths), you can see that you can divide the numerator and the denominator by 2 and get an answer of 2/10 = 1/5. *** Actually 0.2% can be further explained as a decimal. The point is that this number (0.2%) is truly a % so it is not in pure decimal form. If you look at the percentage it is 0.2% and it is in the tens place. To move it to a true decimal you would move the decimal 2 times to the left making it 0.002.
