If your instruction shows or describes a preferred method, saying what it is could be helpful.
This can be reformed as concentrations of milk as fractions of each sample.
The concentrations of each sample are , , , .
Taking equal amount from each and combining these amounts means you have mixed 4 equal parts of the different milk concentrations.
, the mixture fraction as milk.
The lowest denominator needed for handling the arithmetic is .
continue this;
you will have the resulting fraction of mixture as milk. Change into the other ratio notation accordingly to finish.
