Question

У светофора остановились 10 автомашин:2 из них грузовые,5 легковых,остальные автобусы,Какую часть всех автомашин составляют грузовые автомашины? легковые автомашины? автобусы ?

Answer 1

Грузовые 2/10 легковые 5/10 и автобусы 3/10

Answer 2

10машин-100%
грузовые-2
легковые-5
автобусы-?
(2+5)-10=3(автобуса)-на светофоре
2-20% грузовые
5-50% легковые
3-30% автобусы
Ответ: 20%,50%,30%.

Answer 3

Calculation of the Proportions of Different Types of Vehicles

To calculate the proportions of different types of vehicles among the 10 cars stopped at the traffic light, we need to know the number of each type of vehicle. From the given information, we know that there are 2 trucks, 5 cars, and the remaining vehicles are buses.

To find the proportion of trucks, we divide the number of trucks by the total number of vehicles:

Proportion of trucks = Number of trucks / Total number of vehicles

Proportion of trucks = 2 / 10 = 0.2

Therefore, 20% of all the vehicles are trucks.

To find the proportion of cars, we divide the number of cars by the total number of vehicles:

Proportion of cars = Number of cars / Total number of vehicles

Proportion of cars = 5 / 10 = 0.5

Therefore, 50% of all the vehicles are cars.

To find the proportion of buses, we subtract the proportions of trucks and cars from 1, since the remaining vehicles are buses:

Proportion of buses = 1 - (Proportion of trucks + Proportion of cars)

Proportion of buses = 1 - (0.2 + 0.5) = 1 - 0.7 = 0.3

Therefore, 30% of all the vehicles are buses.

Please note that the proportions are calculated based on the given information and assume that there are no other types of vehicles present among the 10 cars stopped at the traffic light.
