The law of constant/definite proportions states that every pure substance always contains the same elements combined in the same proportions by weight.
For instance, water is always composed by 89% percent oxygen and 11% hydrogen. This ratio is constant in nature. This means that the amalgamation of different hydrogen and oxygen ratios will result in a different substance.
Another example is vinegar ( C X 2 H X 4 O X 2 ). If and only if we have 2 atoms of oxygen, 4 atoms of hydrogen and 2 atoms of carbon in the composition we get vinegar, otherwise it is a different substance.
