Question

6. Три класса школьников сажали деревья. Первый класс посадил 0,35 всех деревьев, второй класс - от оставшихся деревьев, а третий класс – остальные 260 деревьев. Сколько всего деревьев посадили три класса?7. В первом баке было 55 л масла, а во втором 45 л. После того как из первого бака наполнили 8 бутылей. А из второго 6 таких же бутылей, масла в баках стало поровну. Сколько масла входит в одну бутыль?

Answer 1

6.Первый класс посадил 35\100 это = 7/20

Второй класс посадил 3/5 это = 12/20

Третий класс посадил 260 это = 1/20 = (7/20+12/20)

 всего деревьев 260*20 =5200

 всего было посаженно 5200 деревьев

Question 6: Три класса школьников сажали деревья. Первый класс посадил 0,35 всех деревьев, второй класс - от оставшихся деревьев, а третий класс – остальные 260 деревьев. Сколько всего деревьев посадили три класса?

To find out how many trees were planted by the three classes, we need to calculate the total number of trees planted by each class and then add them together.

Let's break it down step by step:

1. The first class planted 0.35 (35%) of all the trees. 2. The second class planted the remaining trees after the first class, which is calculated by subtracting the trees planted by the first class from the total number of trees. 3. The third class planted the remaining 260 trees.

To calculate the total number of trees planted by the three classes, we can follow these steps:

1. Calculate the total number of trees planted by the first class: 0.35 * total number of trees. 2. Calculate the total number of trees planted by the second class: (total number of trees - trees planted by the first class). 3. Calculate the total number of trees planted by the third class: 260 trees. 4. Add the number of trees planted by each class together to get the total number of trees planted.

Let's calculate it:

1. The total number of trees planted by the first class is 0.35 multiplied by the total number of trees. 2. The total number of trees planted by the second class is the difference between the total number of trees and the number of trees planted by the first class. 3. The total number of trees planted by the third class is 260 trees. 4. Finally, we add the number of trees planted by each class together to get the total number of trees planted.

Let's calculate it:

Step 1: Calculate the total number of trees planted by the first class: - The first class planted 0.35 of all the trees.

Step 2: Calculate the total number of trees planted by the second class: - The second class planted the remaining trees after the first class.

Step 3: Calculate the total number of trees planted by the third class: - The third class planted the remaining 260 trees.

Step 4: Add the number of trees planted by each class together to get the total number of trees planted.

Let's calculate it:

1. The total number of trees planted by the first class is 0.35 multiplied by the total number of trees. 2. The total number of trees planted by the second class is the difference between the total number of trees and the number of trees planted by the first class. 3. The total number of trees planted by the third class is 260 trees. 4. Finally, we add the number of trees planted by each class together to get the total number of trees planted.

Let's calculate it:

Step 1: Calculate the total number of trees planted by the first class: - The first class planted 0.35 of all the trees.
