ANSWERS: 2

1242017 You have two unknowns and only one equation. The only way to solve that is "guess and check".

Let's call m the ratio of [Quantity from container 1] / [Quantity from container 2]. We can write the content of the mix in matrix notation as follows: [m*(5; 1) + 1*(1; 3) ]*k The matrix sum yields: (5m+1; m+3)*k. The first and second elements of the matrix are the quantities of a and b. Because we want in the end the same quantities of a and b, k doesn't play a role and we can write: 5m+1 = m+3 which resolve in m = 1/2.
