Answer 2

Problem 1: Number of notebooks bought by Masha and Sasha

To find out how many notebooks Sasha bought, we need to determine the number of notebooks Masha bought first. We know that Masha bought 23 notebooks and Sasha bought 12 notebooks less than Masha. Therefore, the number of notebooks Sasha bought can be calculated by subtracting 12 from the number of notebooks Masha bought.

Let's calculate it step by step:

1. Masha bought 23 notebooks. 2. Sasha bought 12 notebooks less than Masha.

To find the number of notebooks Sasha bought, we subtract 12 from 23:

Number of notebooks Sasha bought = 23 - 12 = 11 notebooks.

Therefore, Sasha bought 11 notebooks.

Problem 2: Total number of costumes sewn in 3 days

To find the total number of costumes sewn in 3 days, we need to add the number of costumes sewn on each day.

Let's calculate it step by step:

1. On the first day, 28 costumes were sewn. 2. On the second day, 15 costumes more than the first day were sewn. 3. On the third day, 5 costumes more than the first day were sewn.

To find the total number of costumes sewn in 3 days, we add the number of costumes sewn on each day:

Total number of costumes sewn = 28 + (28 + 15) + (28 + 5) = 28 + 43 + 33 = 104 costumes.

Therefore, a total of 104 costumes were sewn in 3 days.

Problem 3: Total number of badges collected by Vasya

To find the total number of badges collected by Vasya, we need to add the number of badges Vasya has to the number of badges Kolya has.

Let's calculate it step by step:

1. Kolya has 47 badges. 2. Vasya has 26 badges more than Kolya.

To find the total number of badges Vasya has, we add 26 to the number of badges Kolya has:

Total number of badges Vasya has = 47 + 26 = 73 badges.

Therefore, Vasya has a total of 73 badges.

Problem 4: Total number of animals on the farm

To find the total number of animals on the farm, we need to add the number of cows to the number of calves.

Let's calculate it step by step:

1. There are 47 cows on the farm. 2. There are 28 calves on the farm.

To find the total number of animals on the farm, we add the number of cows to the number of calves:

Total number of animals on the farm = 47 + 28 = 75 animals.

Therefore, there are a total of 75 animals on the farm.

Problem 5: Total number of kilograms of plums left in the warehouse

To find the total number of kilograms of plums left in the warehouse, we need to subtract the number of kilograms of plums sold from the total number of kilograms of plums in the warehouse.

Let's calculate it step by step:

1. There were 3 boxes of plums in the warehouse. 2. The first box contained 6 kg of plums. 3. The second box contained 8 kg of plums. 4. The third box contained 4 kg of plums. 5. 5 kg of plums were sold during the day.

To find the total number of kilograms of plums left in the warehouse, we subtract the number of kilograms of plums sold from the total number of kilograms of plums in the warehouse:

Total number of kilograms of plums left in the warehouse = (6 + 8 + 4) - 5 = 13 kg.

Therefore, there are a total of 13 kilograms of plums left in the warehouse.
