Question

автобусы составляют 5/14 всех единиц транспорта, имеющихся в автопарке, грузовые автомобили - 7/18 остальных единиц транспорта. еще в автопарке есть 33 легковых автомобиля. сколько всего единиц транспорта в автопарке?​

Answer 1

Ответ:

129 15/16(скорее всего опечатка)

Если легковых 32, то ответ 126 машин всего.

Пошаговое объяснение:

Приводим первые две дроби к общему знаменателю и сложим. Получилось:

5/14 + 7/18 = 47/63 занимают автобусы и грузовые вместе.

1 - 47/63 = 16/63 - легковые

Мы знаем, что легковых 33 штуки, то есть 1/63 парка будет составлять 33/16 автомобиля. теперь умножим 33/16 на 63 и узнаем сколько всего было машин. Ответ 129 15/16. Скорее всего, в задании опечатка, судя по кривому ответу. Но если в условии 32 легковых машины, то ответ: 126

Answer 2

Calculation of Total Units of Transport in the Fleet

To calculate the total number of units of transport in the fleet, we need to determine the proportion of buses and trucks in the fleet and add the number of passenger cars.

Given the information provided: - Buses make up 5/14 of all units of transport in the fleet. - Trucks make up 7/18 of the remaining units of transport. - There are 33 passenger cars in the fleet.

Let's calculate the total number of units of transport in the fleet step by step:

1. Calculate the proportion of buses in the fleet: - Buses make up 5/14 of all units of transport. - Let's assume the total number of units of transport in the fleet is represented by x. - The number of buses in the fleet can be calculated as (5/14) * x.

2. Calculate the proportion of trucks in the fleet: - Trucks make up 7/18 of the remaining units of transport. - The remaining units of transport can be calculated as (1 - 5/14) * x. - The number of trucks in the fleet can be calculated as (7/18) * (1 - 5/14) * x.

3. Add the number of passenger cars: - The number of passenger cars in the fleet is given as 33.

4. Calculate the total number of units of transport in the fleet: - The total number of units of transport in the fleet is the sum of the number of buses, trucks, and passenger cars.

Let's perform the calculations:

1. Number of buses in the fleet: - Number of buses = (5/14) * x.

2. Number of trucks in the fleet: - Number of trucks = (7/18) * (1 - 5/14) * x.

3. Number of passenger cars in the fleet: - Number of passenger cars = 33.

4. Total number of units of transport in the fleet: - Total = Number of buses + Number of trucks + Number of passenger cars.

Please note that the exact value of x (the total number of units of transport in the fleet) cannot be determined with the given information. However, we can calculate the proportions of buses and trucks in the fleet based on the given fractions and the remaining units of transport.

Let's summarize the calculations:

- Number of buses in the fleet: (5/14) * x - Number of trucks in the fleet: (7/18) * (1 - 5/14) * x - Number of passenger cars in the fleet: 33 - Total number of units of transport in the fleet: (5/14) * x + (7/18) * (1 - 5/14) * x + 33

Please note that the exact value of the total number of units of transport in the fleet cannot be determined without knowing the value of x.
