In AB, 2 g of A combines with 5 g of B.
So, 4 g of A combines with 10 g of B.
In AB2, 2g of B combines with 10 g of B, So 4g of A combines with 20 g of B.
In A2B3 , 4G of B combines with 5 g of B.
In A2B3 4 g of B combined with 15 g of B.
So, the ratio between different masses of B which combine with fixed mass (4g) of A is 10: 20: 5: 15, that is, 2: 4: 1: 3.
Hence, the ratio is simple. Therefore, the law of multiple proportions is applicable.
