To find the ratio of the number of dominoes still standing to the total number of dominoes, we first need to calculate the number of dominoes that are still standing.
The total number of dominoes is 94, and since 23 of them have fallen over, the number of standing dominoes can be calculated as follows:
\[ \text{Number of standing dominoes} = \text{Total dominoes} - \text{Fallen dominoes} \]
Substituting the values:
\[ \text{Number of standing dominoes} = 94 - 23 = 71 \]
Now, we need to find the ratio of the number of standing dominoes to the total number of dominoes:
\[ \text{Ratio} = \frac{\text{Number of standing dominoes}}{\text{Total number of dominoes}} = \frac{71}{94} \]
This ratio \( \frac{71}{94} \) is already in its simplest form, as 71 is a prime number and does not divide 94.
Thus, the final answer is:
\[ \frac{71}{94} \]
