Problem Analysis

The problem states that a farmer has 4 horses and 9 cows. The horses require 135 kg of hay per month, while three cows require the same amount of hay as seven horses. We need to calculate the total amount of hay the farmer should spend on all the horses and cows each month.

Solution

To solve this problem, we can break it down into smaller steps:

1. Calculate the amount of hay required for three cows. 2. Calculate the amount of hay required for seven horses. 3. Calculate the total amount of hay required for all the horses and cows.

Let's calculate each step in detail.

Step 1: Calculate the amount of hay required for three cows

According to the problem, three cows require the same amount of hay as seven horses. Therefore, we can calculate the amount of hay required for three cows by dividing the amount of hay required for seven horses by 7 and then multiplying it by 3.

Let's calculate it: - Amount of hay required for seven horses = 135 kg/month- Amount of hay required for three cows = (Amount of hay required for seven horses / 7) * 3

Step 2: Calculate the amount of hay required for seven horses

According to the problem, seven horses require 135 kg of hay per month.

Step 3: Calculate the total amount of hay required for all the horses and cows

To calculate the total amount of hay required for all the horses and cows, we need to add the amount of hay required for seven horses and the amount of hay required for three cows.

Let's calculate it: - Total amount of hay required = Amount of hay required for seven horses + Amount of hay required for three cows

Now, let's calculate each step.

Calculation

Step 1: Calculate the amount of hay required for three cows: - Amount of hay required for seven horses = 135 kg/month- Amount of hay required for three cows = (135 kg/month / 7) * 3

Step 2: Calculate the amount of hay required for seven horses: - Amount of hay required for seven horses = 135 kg/month Step 3: Calculate the total amount of hay required for all the horses and cows: - Total amount of hay required = Amount of hay required for seven horses + Amount of hay required for three cows

Let's calculate the values.

Calculation Results

Step 1: Calculate the amount of hay required for three cows: - Amount of hay required for seven horses = 135 kg/month- Amount of hay required for three cows = (135 kg/month / 7) * 3 = 45 kg/month

Step 2: Calculate the amount of hay required for seven horses: - Amount of hay required for seven horses = 135 kg/month Step 3: Calculate the total amount of hay required for all the horses and cows: - Total amount of hay required = Amount of hay required for seven horses + Amount of hay required for three cows = 135 kg/month + 45 kg/month = 180 kg/month

Answer

The farmer should spend 180 kilograms of hay every month on all the horses and cows.
