Question

Масса 15,5 л керосина равна 12,4 кг. Найдите массу 20 л керосина

Answer 1

12.4 : 15.5 = 0.8 кг весит 1 литр керосина

0.8 * 20 = 16  кг весит 20 л керосина

Answer 2

To find the mass of 20 liters of kerosene, we can use a proportion to relate the volumes and masses of the kerosene.

Given: Volume of kerosene: 15.5 liters Mass of kerosene: 12.4 kg

Let's assume the mass of 20 liters of kerosene is "x" kg.

We can set up a proportion:

Mass (kg) / Volume (liters) = Mass (kg) / Volume (liters)

Using the given values:

12.4 kg / 15.5 liters = x kg / 20 liters

Now, let's solve for "x":

x = (12.4 kg / 15.5 liters) * 20 liters

x = 1.6 kg (approximately)

Therefore, the mass of 20 liters of kerosene is approximately 1.6 kg.
