3/12*3/12*3/12

To multiply fractions, you multiply the numerators together and the denominators together:

3/12 * 3/12 * 3/12 = (3 * 3 * 3) / (12 * 12 * 12)

= 27/1728

Simplifying this fraction, we can divide the numerator and denominator by their greatest common divisor, which is 9:

27/1728 = (27 ÷ 9) / (1728 ÷ 9)

= 3/192

Therefore, 3/12 * 3/12 * 3/12 simplifies to 3/192.
