On the first day of fishing season, 70% of the 125 people fishing caught fish. Find what percent of the people caught fish.

Your problem states that 70% caught fish.

To find the percentage of people who caught fish, we can use the following formula:

Percentage = (Number of people who caught fish / Total number of people) * 100

In this case, the number of people who caught fish is 70% of the total number of people fishing, which is equivalent to 70/100 * 125 = 0.7 * 125 = 87.5 people.

Now we can substitute these values into the formula to find the percentage:

Percentage = (87.5 / 125) * 100 = 0.7 * 100 = 70%

Therefore, 70% of the 125 people fishing caught fish.
