Question

Три студенческих отряда посадили 2800 деревьев первый отряд посадил 40% всех деревьев второй 28% сколько деревьев посадил третий отряд

Answer 1

2800*(1-0.4-0.28)=2800*0.32=896

Answer 2

2800-Это 100%
1)40%+28%=68%-Это сколько процентов посадили 2 отряда
2)2800:100=28-Это чему равен один процент
3)68*28=1904-Сколько деревьев посадили два отряда
4)2800-1904=896-деревьев посадил третий отряд 
5)Если надо вот в процентах 896:28=32%

Answer 3

Calculating the Number of Trees Planted by the Third Team

To calculate the number of trees planted by the third team, we can use the information provided about the first and second teams.

The first team planted 40% of all the trees, and the second team planted 28% of all the trees.

Let's calculate the percentage of trees planted by the third team.

Step 1: Calculate the percentage of trees planted by the third team. Step 2: Use the total number of trees planted to find the number of trees planted by the third team.

Let's proceed with the calculation.

Calculation

The total percentage of trees planted by the first and second teams is 40% + 28% = 68%.

This means that the third team planted 100% - 68% = 32% of the trees.

If the total number of trees planted is 2800, then the number of trees planted by the third team is 32% of 2800.

Result

The number of trees planted by the third team is 896 trees.

This calculation is based on the information provided and the assumption that the total number of trees planted is 2800.
