Problem Analysis

Kostya bought 8 fish from a pet store, which is 40 fish less than the number of fish remaining in the store's aquarium. We need to determine how many fish are left in the aquarium and calculate the ratio of the number of fish Kostya bought to the number of fish remaining in the aquarium.

Solution

Let's denote the number of fish remaining in the aquarium as x.

According to the given information, Kostya bought 8 fish, which is 40 fish less than the number of fish remaining in the aquarium. This can be expressed as the equation:

x - 8 = 40

To find the value of x, we can solve this equation:

x = 40 + 8

Simplifying the equation, we find:

x = 48

Therefore, there are 48 fish remaining in the aquarium.

To calculate the ratio of the number of fish Kostya bought to the number of fish remaining in the aquarium, we divide the number of fish Kostya bought (8) by the number of fish remaining in the aquarium (48):

Ratio = 8 / 48 = 1/6

So, Kostya bought 1/6 times fewer fish than the number of fish remaining in the aquarium.

Answer

There are 48 fish remaining in the aquarium. Kostya bought fish in a ratio of 1/6 compared to the number of fish remaining in the aquarium.
