Calculating the Number of Seedlings Planted

To calculate the number of seedlings planted on the first and second days, we can use the information provided.

- On the first day, the workers planted one-seventh of all the seedlings. - This is two times less than what they planted on the second day.

Let's calculate the number of seedlings planted on each day.

First Day:

The workers planted one-seventh of all the seedlings on the first day.

Number of Seedlings Planted on the First Day: To find the number of seedlings planted on the first day, we can use the following formula: \[ \text{Number of Seedlings Planted on the First Day} = \frac{1}{7} \times \text{Total Number of Seedlings} \]

Second Day:

The workers planted two times more than what they planted on the first day.

Number of Seedlings Planted on the Second Day: To find the number of seedlings planted on the second day, we can use the following formula: \[ \text{Number of Seedlings Planted on the Second Day} = 2 \times \left( \frac{1}{7} \times \text{Total Number of Seedlings} \right) \]

Let's calculate the number of seedlings planted on each day using the given information.

Calculation:

Given that the workers need to plant 350 seedlings, we can calculate the number of seedlings planted on the first and second days.

Total Number of Seedlings: 350

Number of Seedlings Planted on the First Day: \[ \frac{1}{7} \times 350 = 50 \]

Number of Seedlings Planted on the Second Day: \[ 2 \times \left( \frac{1}{7} \times 350 \right) = 100 \]

Conclusion:

Therefore, the workers planted 50 seedlings on the first day and 100 seedlings on the second day.
