Question

Протягом двох днів робітник виготовив деяку кількість деталей. За перший день він виготовив 9/16 усіх деталей,а за другий- на 9 деталей менше,ніж за перший. Скільки делей виготовив робітник за два дні?

Answer 1

За второй день рабочий изготовил 7/16 всех деталей , но на 9/16- 7/16 = 2/16 =1/8 меньше , чем в первый день или на 9 деталей меньше . Отсюда всего деталей было 9 / 1/8 = 72 детали
Ответ  : За два дня работник изготовил 72 детали

Answer 2

Problem Analysis

We are given that a worker produced a certain number of parts over the course of two days. On the first day, the worker produced 9/16 of all the parts. On the second day, the worker produced 9 fewer parts than on the first day. We need to determine the total number of parts produced by the worker over the two days.

Solution

Let's denote the total number of parts produced by the worker over the two days as x.

According to the given information, on the first day, the worker produced 9/16 of all the parts. This can be represented as:

First day's production = (9/16) * x

On the second day, the worker produced 9 fewer parts than on the first day. This can be represented as:

Second day's production = (9/16) * x - 9

To find the total number of parts produced over the two days, we need to add the first day's production and the second day's production:

Total production = First day's production + Second day's production

Substituting the values we derived earlier:

Total production = (9/16) * x + ((9/16) * x - 9)

Simplifying the equation:

Total production = (9/16) * x + (9/16) * x - 9

Total production = (18/16) * x - 9

Now, we can solve for x to find the total number of parts produced over the two days.

Calculation

Let's calculate the total number of parts produced by the worker over the two days.

Total production = (18/16) * x - 9

Since we don't have the exact value of x, we cannot calculate the total number of parts produced without additional information.

Please provide the value of x or any other relevant information to proceed with the calculation.
