Question

Пакет сухого корма трём собакам хватает на 8 дней. На сколько дней хватит этого корма 4 собакам?

Answer 1

(x+y+z)/3=8
(x+y+z+a)/4=x

x+y+z=24
x+y+z+a=4x
a=4x-24
4x-24=0
x=6(дней)

Answer 2

To find out how many days the package of dry food will last for 4 dogs, we can use a simple proportion:

Let's assume that the package of dry food lasts for "x" days for 4 dogs.

We know that the package lasts for 8 days for 3 dogs. So, the proportion can be set up as follows:

3 dogs / 8 days = 4 dogs / x days

Now, we can solve for "x":

3 * x = 4 * 8

3x = 32

x = 32 / 3

x ≈ 10.67

So, the package of dry food will last for approximately 10.67 days for 4 dogs. Since we cannot have a fraction of a day, we round it to the nearest whole number.

Therefore, the package will last for 11 days for 4 dogs.
