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.
