Question

У фермера 4 лошади и 9 коров. Лошади требуется на месяц 135 кг сена, а трём коровам столько сена, сколько необходимо семи лошадям. Сколько кг сена должен расходовать фермер ежемесячно на всех лошадей и коров?Помогите пожалуйста!

Answer 1

1)135•4=540кг(на всех лошадей)
2)135•7=945кг(трем коровам)
3)945:3=315кг(одной корове)
4)315•9=2835кг(всем коровам)
5)540кг+2835кг=3375кг (на всех животных в месяц)

Answer 2

Calculation of Hay Consumption for Horses and Cows

To calculate the total amount of hay that the farmer needs to spend on all the horses and cows, we need to determine the hay consumption for each animal and then sum them up.

Given information: - The farmer has 4 horses and 9 cows. - The horses require 135 kg of hay per month. - Three cows require the same amount of hay as seven horses.

Let's break down the calculation step by step:

1. Calculate the hay consumption for three cows: - Since three cows require the same amount of hay as seven horses, we can equate their consumption: 3 cows = 7 horses. - Therefore, the hay consumption for three cows is also 135 kg per month.

2. Calculate the hay consumption for one cow: - To find the hay consumption for one cow, we divide the hay consumption for three cows by three: 135 kg / 3 = 45 kg.

3. Calculate the total hay consumption for nine cows: - Multiply the hay consumption for one cow by the number of cows: 45 kg/cow * 9 cows = 405 kg.

4. Calculate the total hay consumption for four horses: - Multiply the hay consumption per horse by the number of horses: 135 kg/horse * 4 horses = 540 kg.

5. Calculate the total hay consumption for all horses and cows: - Add the hay consumption for horses and cows: 540 kg + 405 kg = 945 kg.

Therefore, the farmer needs to spend 945 kg of hay every month to feed all the horses and cows.

Please note that the calculations are based on the given information and assumptions.
