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.
