To find a ratio equivalent to \( \frac{9}{78} \), you can simplify the fraction by finding the greatest common divisor (GCD) of 9 and 78.

  1. Finding the GCD: The factors of 9 are 1, 3, and 9. The factors of 78 are 1, 2, 3, 6, 13, 26, 39, and 78. The largest common factor is 3.

  2. Dividing both the numerator and the denominator by the GCD: \[ \frac{9 \div 3}{78 \div 3} = \frac{3}{26} \]

Thus, the ratio equivalent to \( \frac{9}{78} \) is \( \frac{3}{26} \).

So, the correct response is: 3/26
