To convert the decimal 0.13 into a fraction, follow these steps:
- Identify the decimal: 0.13 can be expressed as \( \frac{13}{100} \) because there are two digits after the decimal point.
- Simplify the fraction if possible: In this case, 13 is a prime number and does not have any common factors with 100, so \( \frac{13}{100} \) is already in its simplest form.
Thus, \( 0.13 \) as a fraction is \( \frac{13}{100} \).
