Correct Answer - Option 1 : 0.0000001

**Given:**

The one-hundredth of centimeter when written in terms of kilometers is as shown below.

**Calculation:**

As 1 km = 1000 m ( where km = kilometer, m = meter )

And 1 m = 100 cm ( where cm = centimeter )

Now, as given in the question one hundredth ( 1/100 ) of 1 cm

⇒ As, we can see 1 km = 105 cm

⇒ ( 1 cm )/ ( 100× 105 )

**∴ 10-7 = 0.0000001 (The one-hundredth of centimeter)**
