Final answer:
To express repeating decimals as fractions, observe the repeating pattern and represent it as a fraction.
Step-by-step explanation:
When expressing repeating decimals as fractions, we can make a conjecture based on the pattern of the decimal. For example, if we have the repeating decimal 0.3333..., we can represent it as the fraction 1/3 since the digit 3 repeats indefinitely. Similarly, the decimal 0.6666... can be represented as the fraction 2/3. The key is to identify the repeating pattern and express it as a fraction.
