If the number female fish is 25 and the male fish is 5 in 100meters. Find the number of female fish in breeding pond which has area of 8000meters?

If the ratio of female fish to male fish is 25:5, then the total number of fish in the 100-meter pond is 25 + 5 = 30.

To find the number of female fish in the breeding pond with an area of 8000 meters, we can set up a proportion:

100 meters is to 30 fish as 8000 meters is to x fish

100/8000 = 30/x

Cross multiplying, we get:

100x = 240,000

Dividing by 100, we find:

x = 2400

Therefore, there are 2400 female fish in the breeding pond.

Step 1: Calculate the ratio of female to male fish

Female fish : Male fish = 25 : 5 = 5 : 1

Step 2: Determine the total number of fish in the breeding pond

Let's assume the total number of fish in the breeding pond is x.

Step 3: Set up an equation based on the ratio and the total number of fish

5/1 = x/8000

Step 4: Solve for x

Cross-multiply: 5 - 8000 = x - 1
Simplify: 40000 = x

Therefore, the number of female fish in the breeding pond is 40000.
