1) (20+15)-5=30
2способ
1)(20-5)+15=30
3способ
1)(15-5)+20=30
Ответ:30

Answer 2

1) 20-5=15 литров воды осталось в 1 бочке.
15+15=30 литров воды осталось в бочках.
2) 15-5=10 литров воды осталось во второй бочке.
10+20=30 литров воды осталось в бочках.
3) 20+15=35 литров воды было всего в бочках.
35-5=30 литров воды осталось в бочках.

Answer 3

Calculation 1:

To find out how many buckets of water are left in the barrels, we need to subtract the amount of water taken for watering from the total amount of water in the barrels.

In one barrel, there were 20 buckets of water, and in the other barrel, there were 15 buckets of water.

For watering, 5 buckets of water were taken.

To calculate the remaining buckets of water, we subtract the amount taken from the total amount in each barrel:

- In the first barrel: 20 buckets - 5 buckets = 15 buckets of water remaining. - In the second barrel: 15 buckets - 5 buckets = 10 buckets of water remaining.

Therefore, there are 15 buckets of water left in the first barrel and 10 buckets of water left in the second barrel.

Calculation 2:

Another way to calculate the remaining buckets of water is by adding the total amount of water in both barrels and then subtracting the amount taken for watering.

- Total amount of water in both barrels: 20 buckets + 15 buckets = 35 buckets of water. - Amount taken for watering: 5 buckets.

To find the remaining buckets of water, we subtract the amount taken from the total amount:

35 buckets - 5 buckets = 30 buckets of water remaining.

Therefore, there are 30 buckets of water left in the barrels.

Calculation 3:

We can also calculate the remaining buckets of water by subtracting the amount taken for watering from each barrel individually.

- In the first barrel: 20 buckets - 5 buckets = 15 buckets of water remaining. - In the second barrel: 15 buckets - 5 buckets = 10 buckets of water remaining.

Therefore, there are 15 buckets of water left in the first barrel and 10 buckets of water left in the second barrel.

In summary, there are 15 buckets of water left in the first barrel and 10 buckets of water left in the second barrel, regardless of the calculation method used.
