Question

Токарь выполнил до обеда задания. после обеда он обтачил половину оставшихся деателей да ещё 24 деталей и выполнил все задание сколько деателей токарь обтачил за день ​

Answer 1

Ответ:

108

Пошаговое объяснение:

после обеда 1-5/9=4/9

2/9 половина оставшейся это по условию 24 детали

1/9 это 24/2=12 деталей

1/9 нормы 12 деталей

1 нормы 108

Answer 2

Ответ:

Пошаговое объяснение:

9/9-5/9=4/9 должен обточить после обеда

Половина 4/9 =2/9

2/9 составляет 24 детали

Чтобы узнать целое по его части нужно данное число разделить на дробь, т.е. умножить на дробь, обратную данной дроби

24÷2/9=24×9/2=12×9=108 деталей всего обточил токарь за день

Answer 3

Task Completion by the Lathe Operator

The lathe operator completed a certain number of tasks before and after lunch. Let's calculate the total number of parts he machined in a day.

Tasks Completed: - Before lunch: Completed initial tasks. - After lunch: Machined half of the remaining parts and an additional 24 parts.

Calculation of Total Parts Machined

To calculate the total number of parts machined by the lathe operator in a day, we can follow these steps:

1. Initial Tasks Completed Before Lunch: - Let's denote the initial number of parts completed before lunch as x.

2. Remaining Tasks After Lunch: - The remaining tasks after lunch would be the total tasks minus the initial tasks completed before lunch. - The lathe operator machined half of the remaining tasks and an additional 24 parts.

3. Total Tasks Completed: - The total tasks completed in a day would be the sum of the initial tasks completed before lunch and the tasks completed after lunch.

Calculation

Let's denote the total number of parts machined in a day as T.

- Initial tasks completed before lunch: x - Remaining tasks after lunch: T - x - Tasks completed after lunch: (T - x) / 2 + 24 - Total tasks completed in a day: x + (T - x) / 2 + 24

We can use this information to calculate the total number of parts machined by the lathe operator in a day.
