To find out what percent of the campers Mr. Green helped, we can set up a proportion.
We know that:
- The number of campers is 600.
- The number of campers Mr. Green helped is 6.
We want to find the percentage of campers Mr. Green helped. We can express this as:
\[ \frac{\text{Number of campers helped}}{\text{Total number of campers}} = \frac{6}{600} \]
To find the percentage, we can set up the equation:
\[ \frac{6}{600} = \frac{x}{100} \]
where \( x \) is the percentage we want to find.
Now, we can cross-multiply to solve for \( x \):
\[ 6 \times 100 = 600 \times x \]
\[ 600 = 600x \]
Next, divide both sides by 600:
\[ x = \frac{600}{600} \]
\[ x = 1 \]
Thus, Mr. Green helped 1% of the campers yesterday.
So, the final answer is: Mr. Green helped 1% of the campers yesterday.
