To convert the decimal 0.81 into a fraction, you can follow these steps:
1. Write the decimal as a fraction with 1 in the denominator:
\( 0.81 = \frac{0.81}{1} \)
2. To eliminate the decimal, multiply the numerator and the denominator by 100 (since there are two decimal places):
\( \frac{0.81 \times 100}{1 \times 100} = \frac{81}{100} \)
3. Now, check if the fraction can be simplified. The greatest common divisor (GCD) of 81 and 100 is 1, so the fraction is already in its simplest form.
Thus, \( 0.81 \) as a fraction is \( \frac{81}{100} \).
