Question

In direct proportion , the ------ of both quantities remains same.​

Answer 1

Answer:

Direct Proportion

This is direct proportionality. Let's take two quantities, x and y which are believed to be in direct proportion. Now, what would that mean? It means, that these two quantities, x and y, will increase and decrease in such a manner that the ratio of their corresponding values always remains constant.

Answer 2

Answer:

If two quantities x and y vary (change) together in such a manner that the ratio of their corresponding values remains constant, then x and y are said to be in direct proportion.

• if two quantities x and y vary (change) in such a manner that an increase in x causes a proportional decrease in y (and vice versa), then x and y are said to be inverse proportion.

• If x and y are in a direct proportion, then

• If x and y are in an inverse variation, then xy = constant.
