A herd of 88 horses has 31 white and some black horses. What is the ratio of black horses to all horses Find the number of black horses when the herd has 31 whites.

Answer 1

To find the number of black horses in the herd, you can start by subtracting the number of white horses from the total number of horses:

1. Total horses = 88
2. White horses = 31

Now calculate the number of black horses:

\[ \text{Number of black horses} = \text{Total horses} - \text{White horses} = 88 - 31 = 57 \]

Now we can find the ratio of black horses to all horses. The ratio is given by:

\[ \text{Ratio of black horses to all horses} = \frac{\text{Number of black horses}}{\text{Total horses}} = \frac{57}{88} \]

So, there are 57 black horses in the herd, and the ratio of black horses to all horses is \( \frac{57}{88} \).
