Question

дедушка собрал с огорода за первый час работы 3 9/16 помидоров за второй час работы собрал на 1 7/20 меньше чем за первый час. а третий час работы собрал столько же сколько за первые два часа . сколько килограммов собрал за третий час ? ​

Answer 1

Ответ:

Пошаговое объяснение:

3 9/16 -1 7/20=3 45/80 -1 28/80=2 17/80 кг помидоров собрано за 2-й час.

3 9/16 +2 17/80=3 45/80 +2 17/80=5 62/80=5 31/40=5,775 кг помидоров собрано за 3-й час.

Answer 2

Calculation of Tomato Harvest

To calculate the amount of tomatoes harvested by the grandfather in the third hour, we need to analyze the information provided.

- In the first hour, the grandfather harvested 3 9/16 tomatoes. - In the second hour, he harvested 1 7/20 fewer tomatoes than in the first hour. - In the third hour, he harvested the same amount as in the first two hours.

Let's break down the calculations step by step:

1. First, let's convert the mixed fractions into improper fractions for easier calculations: - 3 9/16 can be converted to 57/16. - 1 7/20 can be converted to 27/20.

2. Next, let's calculate the total number of tomatoes harvested in the first two hours: - In the first hour, the grandfather harvested 57/16 tomatoes. - In the second hour, he harvested 57/16 - 27/20 tomatoes.

3. To find the common denominator, we need to calculate the least common multiple (LCM) of 16 and 20, which is 80.

4. Now, let's convert the fractions to have a common denominator of 80: - 57/16 can be converted to 285/80. - 27/20 can be converted to 108/80.

5. Adding the fractions together, we get: - 285/80 - 108/80 = 177/80.

6. Therefore, the total number of tomatoes harvested in the first two hours is 177/80.

7. Since the grandfather harvested the same amount in the third hour as in the first two hours, the total number of tomatoes harvested in the third hour is also 177/80.

8. To convert the fraction to a mixed number, we divide the numerator by the denominator: - 177 ÷ 80 = 2 remainder 17.

9. The mixed number form of 177/80 is 2 17/80.

Therefore, the grandfather harvested 2 17/80 kilograms of tomatoes in the third hour.
