Question

на одной ферме овцам, кроме других кормов, выдавали на день 420 кг сена, а на другой- 375 кг. На первой ферме овец было на 15 больше, чем на второй. Сколько овец было на каждой ферме, если норма выдачи сена на одну овцу в день одинаковая?

Answer 1

55     40

1) 420000г/(420-375-15)=10500

2) 375000г:40=9375

Answer 2

На сколько больше кг сена выдавали на первой ферме ,чем на второй?

420-375=45кг

Сколько кг сена приходится на одну овцу?

45:15=3кг

Сколько овец было на первой ферме?

420:3=140 овец

Сколько овец было на второй ферме?

375:3=125 овец

Ответ:140 овец,125 овец.

Answer 3

Problem Analysis

We are given two farms where sheep are fed different amounts of hay (420 kg on one farm and 375 kg on the other). The number of sheep on the first farm is 15 more than the number on the second farm. We need to determine the number of sheep on each farm, assuming that the hay distribution per sheep per day is the same on both farms.

Solution

Let's assume that the number of sheep on the second farm is x. Therefore, the number of sheep on the first farm would be x + 15.

We know that the total amount of hay distributed on the first farm is 420 kg, and the total amount of hay distributed on the second farm is 375 kg. Since the hay distribution per sheep per day is the same on both farms, we can set up the following equation:

(420 kg) / (x + 15 sheep) = (375 kg) / (x sheep)

To solve this equation, we can cross-multiply:

(420 kg) * (x sheep) = (375 kg) * (x + 15 sheep)

Simplifying further:

420x = 375x + 5625

Subtracting 375x from both sides:

420x - 375x = 5625

Simplifying:

45x = 5625

Dividing both sides by 45:

x = 125

Therefore, there are 125 sheep on the second farm. Since the number of sheep on the first farm is 15 more, there are 125 + 15 = 140 sheep on the first farm.

Answer

There are 125 sheep on the second farm and 140 sheep on the first farm.
