Answer 1

1)7:10=0,7
2)80:100=0,8
3)0,8-0,7=0,1

Answer 2

Calculating the Weight Difference Between Kerosene and Gasoline

To calculate the weight difference between 1 liter of kerosene and 1 liter of gasoline, we can use the given information about the masses of 10 liters of gasoline and 100 liters of kerosene.

Given: - Mass of 10 liters of gasoline = 7 kg - Mass of 100 liters of kerosene = 80 kg

First, we need to find the mass of 1 liter of each fuel. Then, we can compare the difference in their masses.

Calculating the Mass of 1 Liter of Each Fuel

To find the mass of 1 liter of each fuel, we can use the following calculations:

For gasoline: - Mass of 1 liter of gasoline = (Mass of 10 liters of gasoline) / 10 - Mass of 1 liter of gasoline = 7 kg / 10 - Mass of 1 liter of gasoline = 0.7 kg

For kerosene: - Mass of 1 liter of kerosene = (Mass of 100 liters of kerosene) / 100 - Mass of 1 liter of kerosene = 80 kg / 100 - Mass of 1 liter of kerosene = 0.8 kg

Calculating the Weight Difference

Now, we can calculate the weight difference between 1 liter of kerosene and 1 liter of gasoline:

- Weight difference = Mass of 1 liter of kerosene - Mass of 1 liter of gasoline - Weight difference = 0.8 kg - 0.7 kg - Weight difference = 0.1 kg

Therefore, 1 liter of kerosene is heavier than 1 liter of gasoline by 0.1 kilograms.
