Calculating the Number of Chestnut Trees Planted

To calculate the number of chestnut trees planted, we can use the information provided in the question.

Given: - 684 trees were planted in the park. - One-fourth of the trees were maples. - One-sixth of all the trees were birches. - The rest of the trees were chestnuts.

Let's calculate the number of chestnut trees planted.

Calculation

1. Calculate the number of maples: - 684 trees * (1/4) = 171 maples

2. Calculate the number of birches: - 684 trees * (1/6) = 114 birches

3. Calculate the total number of maples and birches: - 171 maples + 114 birches = 285 maples and birches

4. Calculate the number of chestnuts: - 684 trees - 285 maples and birches = 399 chestnuts

Therefore, the number of chestnut trees planted is 399.

This calculation is based on the given fractions of maples, birches, and the remaining trees being chestnuts.
