Question

Помогите решить задачи: №1: Туристы за 3 дня прошли 72 км. Во 2 день они прошли 60 %, того что прошли в 1 день,а в 3 день две третих того, что прошли во 2 день. Сколько км прошли туристы за все 3 дня? №2: В 3 цехах завода 360 станков. Число станков во 2 цехе составляет 50 %, станков 1 цеха, а число станков в 3 цехе составляет три пятых числа станков 2 цеха. Сколько станков в каждом цехе? p.s. Если что помогите хотя бы с 1 задачей. Пожалуйста!!!!!

Answer 2

Задача 1.(если вопрос: по сколько км прошли в каждый день?
.х-1 день, 0,6х-2 день,6/10х2/3=4/10 - 0,4х-3день
х+0,6х+0,4х=72
2х=72
х=36  (км)- 1 день
36Х0,6=21,6(км)-2 день
36Х0,4=14,4(км) - 3 день
Ответ:36, 21,6 и 14,4км. 
Задача 2.
х-станков в 1 цехе
0,5хстанков во 2 цехе, а в 3цехе : 0,3х станков (3/5=0,6 ; 0,6Х0,5=0,3)
х+0,5х+0,3х=360
1,8х=360
х=200 (ст.)-в 1 цехе;
0,5Х200=100(ст.)-во2 цехе
0,3Х200= 60 (ст.)- в 3 цехе

Answer 3

Task 1: Finding the Distance Traveled by Tourists

To find the distance traveled by the tourists over 3 days, we can use the information provided about the distances covered on each day.

Let's calculate the distance traveled by the tourists over the 3 days.

The tourists covered 72 km in 3 days. On the second day, they covered 60% of what they covered on the first day, and on the third day, they covered two-thirds of what they covered on the second day.

Using this information, we can calculate the distance traveled by the tourists over the 3 days.

Calculation: - Distance covered on the first day: 72 km - Distance covered on the second day: 60% of 72 km = 72 km * 0.60 = 43.2 km - Distance covered on the third day: Two-thirds of the distance covered on the second day = 43.2 km * (2/3) = 28.8 km

Therefore, the total distance covered by the tourists over the 3 days is: 72 km + 43.2 km + 28.8 km = 144 km.

Task 2: Finding the Number of Machines in Each Workshop

To find the number of machines in each workshop, we can use the information provided about the total number of machines and the proportions in each workshop.

Let's calculate the number of machines in each workshop.

Given: - Total number of machines in 3 workshops: 360 - Number of machines in the second workshop is 50% of the machines in the first workshop - Number of machines in the third workshop is three-fifths of the machines in the second workshop

Calculation: Let's assume the number of machines in the first workshop is x.

- Number of machines in the second workshop: 50% of x = 0.50x - Number of machines in the third workshop: Three-fifths of the machines in the second workshop = (3/5) * 0.50x = 0.30x

The sum of the machines in all workshops is 360: x + 0.50x + 0.30x = 360 1.80x = 360 x = 360 / 1.80 x = 200

Therefore, the number of machines in each workshop is: - First workshop: 200 machines - Second workshop: 100 machines - Third workshop: 60 machines
