Question

С дровяного склада в первый день отпустили 420куб.м. дров, что составило 35% имевшихся на складе. Во второй день было отпущено 5\7 того, что отпустили в первый, а остальные дрова распределили между тремя домоуправлениями пропорционально числам 2,625:1, 125:0,75. Сколько куб.м. Дров было отпущено каждому домоуправлению?

Answer 1

1день-420
2 день 420*5/7 =300
35%=0,35
420:0.35=1200 всего дров
1200-420-300=480 осталось
2,625+1,125+0,75=4,5частей
480:4.5=не делится нацело проверь условие

Answer 2

Calculation of the Amount of Firewood Released to Each Housing Management

To calculate the amount of firewood released to each housing management, we need to follow the given information step by step.

1. On the first day, 420 cubic meters of firewood were released, which constituted 35% of the total amount available on the storage.

Calculation: - Let's assume the total amount of firewood on the storage is represented by 'x'. - According to the given information, 35% of 'x' is equal to 420 cubic meters. - We can express this as an equation: 0.35x = 420. - Solving for 'x', we find that x = 420 / 0.35 = 1200 cubic meters.

Therefore, the total amount of firewood available on the storage is 1200 cubic meters.

2. On the second day, 5/7 of the amount released on the first day was released, and the remaining firewood was distributed proportionally among three housing managements.

Calculation: - The amount of firewood released on the second day is 5/7 of the amount released on the first day. - Let's calculate the amount released on the second day: (5/7) * 420 = 300 cubic meters.

- The remaining firewood after the second day is the difference between the total amount available on the storage and the amount released on the first and second days: 1200 - 420 - 300 = 480 cubic meters.

- The firewood is distributed proportionally among three housing managements based on the given ratios: 2,625:1 and 125:0,75.

- Let's calculate the total ratio: 2,625 + 1 + 125 + 0,75 = 3,75.

- Now, we can calculate the amount of firewood distributed to each housing management: - For the first housing management: (2,625 / 3,75) * 480 = 336 cubic meters. - For the second housing management: (1 / 3,75) * 480 = 128 cubic meters. - For the third housing management: (125 / 3,75) * 480 = 16 cubic meters.

Therefore, each housing management received the following amounts of firewood: - The first housing management: 336 cubic meters. - The second housing management: 128 cubic meters. - The third housing management:
