24 of the 27 participants in a triathlon are men and the rest are women. What is the ratio of the number of women participating to the total number of participants?

Write your answer as two numbers separated by a colon (for example, 2:3).

First, let's find out how many women are participating in the triathlon. Since there are 27 participants in total and 24 of them are men, the number of women is:

\[
\text{Number of women} = \text{Total participants} - \text{Number of men} = 27 - 24 = 3
\]

Next, we calculate the ratio of the number of women to the total number of participants. The ratio is:

\[
\text{Ratio} = \frac{\text{Number of women}}{\text{Total participants}} = \frac{3}{27}
\]

We can simplify this ratio by dividing both numbers by their greatest common divisor (GCD), which is 3:

\[
\frac{3 \div 3}{27 \div 3} = \frac{1}{9}
\]

So, the ratio of the number of women participating to the total number of participants is:

**1:9**
