  1. Alright, awesome. Thanks once again for the help, and for descriptions of multiple ways to solve this. I appreciate it! Cheers.
  2. I took the advice and did this problem in the same format as the other question. I did get the answer right (answer key is in the back of the book), but I want to know if I arrived at the answer correctly. This is how I did it: -First I added up the 3 parts of the ratio that weren't given in grams (3+19+5=27). Then I put the two remaining numbers into a fraction (27/7) and divided. That gave me an answer of (3.857) Then I multiplied this by The original information given in the question (3.5g) by (3.857) which gave an answer of (13.545). Lastly I added that amount to the original info (13.545+3.5g). This in turn gave me a final answer of (=17.045g) or simply (17g). -So, am I way out in left field, or was the method used appropriate? (BTW thanks very much for the replies to this post, and for the advice!)
  3. Okay, So This is probably easy compared to most of the problems presented on this website, but it would help immensely if I could recieve some help with it. -The problem is as follows: When mixing a quantity of paints, dyes of four different colours are used in the ratio of 7:3:19:5. If the mass of the first dye used is 3.5g, determine the total mass of the dyes used. -I have Tried to construct an equation for this, but to no avail. This problem I believe is in relation to an earlier, simpler problem: Problem 15. An alloy is made up of metalsA and B in the ratio 2.5:1 by mass. How much ofA has to be added to 6 kg of B to make the alloy? Ratio A:B: :2.5:1 i.e. AB =2.5/1 =2.5 When B=6 kg, A/6 =2.5 from which, A=6×2.5=15kg Any help at all would be highly appreciated.
