Calculating the Amount of Ore Replaced by Scrap Metal

To calculate the amount of ore replaced by scrap metal, we can use the given ratio of 1 kg of scrap metal replacing 2.5 kg of ore.

Given: - 1 kg of scrap metal replaces 2.5 kg of ore

We need to find out how much ore is replaced by 4 tons (4000 kg) of scrap metal.

Calculation:

1. Calculate the amount of ore replaced by 1 kg of scrap metal: - 1 kg of scrap metal replaces 2.5 kg of ore

2. Calculate the amount of ore replaced by 4000 kg of scrap metal: - 1 kg of scrap metal replaces 2.5 kg of ore - 4000 kg of scrap metal replaces (4000 kg * 2.5) kg of ore

Result:

4000 kg of scrap metal replaces 10,000 kg (or 10 tons) of ore.

This calculation is based on the given ratio of 1 kg of scrap metal replacing 2.5 kg of ore.
