Weight 15 liters. of kerosene is 12 kg 300 g. What is the mass of 60 liters of kerosene?

1 way.

Let’s solve the problem using proportion.

Let’s designate as x kg the mass of 60 liters of kerosene.

Let’s make the following entry:

15 liters – 12.3 kg;

60 liters – x kg.

Let’s make the proportion:

15: 60 = 12.3: x.

In terms of the main proportion, the product of its extreme members is equal to the product of averages:

15x = 60 * 12.3;

15x = 738;

x = 738: 15;

x = 49.2.

We find that x = 49.2 kg – the mass of 60 liters of kerosene.

Method 2.

1) 12.3: 15 = 0.82 kg – the mass of one liter of kerosene.

2) 0.82 * 60 = 49.2 kg – the mass of 60 liters of kerosene.

Answer: 49 kg 200 g.
