The Law of Variable Proportions and the Law of Returns to Scale are two different concepts in economics that deal with production functions. Here's how they differ:

1. Time Frame: The Law of Variable Proportions applies to the short run. In the short run, at least one factor of production is fixed. On the other hand, the Law of Returns to Scale applies to the long run. In the long run, all factors of production are variable.

2. Proportions of Inputs: The Law of Variable Proportions deals with variable proportions of inputs. It states that as we increase the quantity of one input while keeping other inputs constant, there will be a point beyond which the marginal product of that input will start to decrease. The Law of Returns to Scale, however, deals with fixed proportions of inputs. It states that if we increase all inputs by the same proportion, the output may increase by more than, less than, or the same proportion.

3. Assumptions about Inputs: The Law of Variable Proportions assumes that one input is kept constant while varying the other. For example, we might increase the amount of labor while keeping the amount of capital constant. The Law of Returns to Scale, however, assumes that all inputs are varied. For example, we might increase both labor and capital by the same proportion.

4. Variation of Inputs: The Law of Variable Proportions assumes that all inputs are varied, but not in the same proportion. On the other hand, the Law of Returns to Scale assumes that one input is kept constant. This is a key difference between the two laws.

In summary, while both laws deal with how changes in inputs affect outputs, they apply to different time frames and make different assumptions about how inputs are varied.
