Question

В цехе имелись токарные,фрезерные и шлифовальные станки. токарные станки составляли пять одиннадцатых всех станков. Шлифовальные составляли две пятых от числа токарных станков. Сколько всего в цехе станков, если известно, что фрезерных станков на 8 меньше чем токарных

Answer 1

1)5/11 умножить на 2/5=2/11 шлиф. 2) 1-(5/11+2/11)=4/11 фрез. 3) 5/11-4/11=1/11- это 8 станков. 1 часть = 8 станков. 4) 8 умнож.11=88 станков всего

Answer 2

Calculating the Total Number of Machines in the Workshop

To calculate the total number of machines in the workshop, we can use the given information about the proportion of lathe, milling, and grinding machines.

Given: - Lathe machines make up 5/11 of all machines. - Grinding machines make up 2/5 of the number of lathe machines. - The number of milling machines is 8 less than the number of lathe machines.

Let's calculate the total number of machines in the workshop step by step.

1. Number of Lathe Machines (L): - Lathe machines make up 5/11 of all machines. - Let's assume the total number of machines is represented by T. - Therefore, the number of lathe machines (L) can be calculated as: ``` L = (5/11) * T ```

2. Number of Grinding Machines (G): - Grinding machines make up 2/5 of the number of lathe machines. - The number of grinding machines (G) can be calculated as: ``` G = (2/5) * L ```

3. Number of Milling Machines (M): - The number of milling machines is 8 less than the number of lathe machines. - The number of milling machines (M) can be calculated as: ``` M = L - 8 ```

4. Total Number of Machines (T): - The total number of machines (T) is the sum of lathe, milling, and grinding machines. - Therefore, the total number of machines (T) can be calculated as: ``` T = L + M + G ```

Let's calculate the total number of machines using the given information.

Calculation

1. Number of Lathe Machines (L): - L = (5/11) * T

2. Number of Grinding Machines (G): - G = (2/5) * L

3. Number of Milling Machines (M): - M = L - 8

4. Total Number of Machines (T): - T = L + M + G

Let's proceed with the calculations.
