Apologies for the previous response. Let's convert the decimal to a fraction.

First, we count the number of decimal places. In this case, there are four decimal places (0.1213).

Next, we write the decimal as a fraction with the decimal places as the numerator and the denominator as a power of 10, based on the number of decimal places.

In this case, the fraction would be:

0.1213 = 1213/10000

So, the correct answer is:

B. 1213/10000
