Answer 1

D. Move the decimal point in 132.9 three places to the left.

Explanation:

Multiplication of a decimal by the nth power of 10:

We move the decimal point n places to the right.

Division of a decimal by the nth power of 10:

We move the decimal point n places to the left.

In this question:

There is a division by 1000, which is the 3rd power of 10, because
`10^3 = 1000`

So, we should move the decimal point three places to the left, and the correct answer is given by option D.
