РЕШАТЬ ПРОПОРЦИЕЙ!БЕЗ ПРОПОРЦИИ- НАРУШЕНИЕВ результате сокращения зарплаты сотрудники стали получать вместо 3000 рублей в неделю 2400 рублей. Сколько процентов новая зарплата составляла от старой зарплаты?

Answer 1

3000 руб - 100% 
2400 руб - х %

3000х= 2400
х= 0,8
0,8 или 80% составляет новая зарплата от старой ⇒ зарплата снизилась на 20%
(100% - 80% = 20%).

Answer 2

Calculating the Percentage of the New Salary Compared to the Old Salary

To calculate the percentage of the new salary compared to the old salary, we can use the proportion method. The proportion method involves setting up a ratio of the new salary to the old salary and then finding the percentage equivalent of that ratio.

In this case, the old salary was 3000 rubles per week, and the new salary is 2400 rubles per week. To find the percentage of the new salary compared to the old salary, we can set up the following proportion:

New Salary / Old Salary = x / 100

Substituting the given values, we have:

2400 / 3000 = x / 100

To solve for x, we can cross-multiply and then divide:

2400 * 100 = 3000 * x

240000 = 3000x

x = 240000 / 3000

x = 80

Therefore, the new salary of 2400 rubles per week represents 80% of the old salary of 3000 rubles per week.

Please note that the information provided above is based on the given context and calculations.
