Andre makes another sculpture that uses 2 2/5 times as much bronze as the small sculpture which is 105/12 bronze. How many kilograms of bronze does this sculpture need? Show your work.
To find the amount of bronze needed for the larger sculpture, we first need to find how much bronze the smaller sculpture needs.
105/12 bronze is equivalent to 8 9/12 bronze, or 8.75 bronze.
The larger sculpture needs 2 2/5 times as much bronze as the smaller sculpture.
2 2/5 times 8.75 bronze is equal to (12/5) * 8.75 or 21 bronze.
Therefore, the larger sculpture needs 21 kilograms of bronze.
