Answer 2

Calculating the Number of Ships

To find out how many ships Petya has in total, we can use the information that he attached sails to 80% of his fleet, which consists of 16 ships.

Let's calculate the total number of ships Petya has:

We can use the following formula to find the total number of ships: \[ \text{Total number of ships} = \frac{\text{Number of ships with sails}}{\text{Percentage with sails}} \times 100 \]

Plugging in the given values: \[ \text{Total number of ships} = \frac{16}{0.80} \times 100 \] \[ \text{Total number of ships} = 20 \]

So, Petya has a total of 20 ships in his fleet.
