An alloy is made from tin and copper. The ratio of weight tin: weight copper is 1: 4. How much tin is needed to make 20g alloy?
This is a question I was asked in a quiz and I still don't know the answer.
Any help would be appreciated ASAP.

20g in 1:4 so you divide 20 by five (ratio splits the 20 in 5) which is equal to 4 per "1" of ratio.

You will need 1x4 = 4g for tin
4x4 = 16g for copper.

I hope that this makes sense.
