As 4.2 g of alloy contain 3.5 g of copper,
Divide both the values by 2,
So,we come to know that for 2.1 g of alloy there is 1.75 g of copper
Now,18.9/2.1=9, so 2.1×9=18.9
1.75×9=15.75
Therefore,for 18.9 g of alloy there is 15.75 g of copper
Divide both the values by 2,
So,we come to know that for 2.1 g of alloy there is 1.75 g of copper
Now,18.9/2.1=9, so 2.1×9=18.9
1.75×9=15.75
Therefore,for 18.9 g of alloy there is 15.75 g of copper
