Завдання №2
1 1/48(одна ціла один сороквосьмих)

Пояснення до завдання №2:
У другий день завезли на 3/16 менше, ніж у перший, тому ми знаходимо, скільки завезли у перший день:
5/12+3/16=29/48(т)
Тепер додаємо і отримуємо відповідь:
5/12+29/48=49/48=1 1/48(т)

Answer 2

Task 1: Calculations

To solve the given expressions, let's calculate each of them step by step.

1. 2/3 + 5/8 - To add these fractions, we need to find a common denominator, which is 24. - 2/3 + 5/8 = 16/24 + 15/24 = 31/24

2. 11/16 - 5/8 - To subtract these fractions, we also need a common denominator, which is 16. - 11/16 - 5/8 = 11/16 - 10/16 = 1/16

3. 6/35 + 3/10 - To add these fractions, we need to find a common denominator, which is 70. - 6/35 + 3/10 = 12/70 + 21/70 = 33/70

4. 7/12 - 3/8 - To subtract these fractions, we need a common denominator, which is 24. - 7/12 - 9/24 = 14/24 - 9/24 = 5/24

5. 8/15 - 4/9 - To subtract these fractions, we need a common denominator, which is 45. - 8/15 - 20/45 = 24/45 - 20/45 = 4/45

6. 3/10 + 4/15 - To add these fractions, we need to find a common denominator, which is 30. - 3/10 + 8/30 = 9/30 + 8/30 = 17/30

Task 2: Word Problem

In the second task, we are given that in the second day, 5/12 tons of potatoes were brought, which is 3/16 tons less than the amount brought on the first day. We need to find the total amount of potatoes brought in two days.

Let's calculate the amount of potatoes brought on the first day: - Amount brought on the first day = 5/12 + 3/16 = 10/24 + 3/24 = 13/24 tons

Now, to find the total amount brought in two days: - Total amount = Amount brought on the first day + Amount brought on the second day - Total amount = 13/24 + 5/12 - Total amount = 13/24 + 10/24 - Total amount = 23/24 tons

So, the total amount of potatoes brought in two days is 23/24 tons.
