# How does 1/(0.0*D) = 100/D?

If D is a nonzero digit in the decimal number 0.0 D, which of the following must be equal to 1 over 0.0 D?

(A) 100 over D (Right Answer)

(B) 10 over D

(C) 1 over D

(D) D over 10

(E) D over 100

_____________________________________

Wouldn't 0.0*D = 0? Therefore, wouldn't the expression, 1/(0.0*D), equal infinity? I don't understand how the two expressions are equal. Thanks in advance.

0.0D is not multiplication.

For instance, if D is 2, 0.0D is 0.02. If D is 9, 0.0D is 0.09.

So if you multiply top and bottom of 1/(0.0D) by 100 you get 100/D.
