Question

Помогите решить задачу: для изготовления 18 одинаковых приборов потребовалось 27 г. платины. Сколько платины потребуется на изготовление 28 таких приборов??

Answer 1

  27 г   -   18 приборов
    х г   -   28 приборов
Составим пропорцию 27 : х  = 18 : 28 ⇒ х = 27 ·28 : 18 = 42 (г)

Answer 2

Task Solution:

To solve this problem, we can use the given information to calculate the amount of platinum required to manufacture 28 identical devices.

Given: - Amount of platinum required for 18 devices = 27 g

Calculation:

We can calculate the amount of platinum required for 28 devices using the following steps:

1. Calculate the amount of platinum required for 1 device: - Amount of platinum for 1 device = Total platinum / Total devices - Amount of platinum for 1 device = 27 g / 18 - Amount of platinum for 1 device = 1.5 g 2. Calculate the amount of platinum required for 28 devices: - Amount of platinum for 28 devices = Amount of platinum for 1 device * 28 - Amount of platinum for 28 devices = 1.5 g * 28 - Amount of platinum for 28 devices = 42 g

Answer:

Therefore, the amount of platinum required for the manufacture of 28 such devices is 42 grams.
