Question

What is the meaning of inversely proportional and directly proportional ?

Answer 1

ditectly proportional means that if one quantity increases then other must be increased...like force is directly proportional to mass if mass is increased we must have to increase force to lift mass..
inversly propirtional means if one quantity increases then other must decrease..like Force is inversely proportional to square of distance between mass...so if distance increasese then force must be decreased..and vice versa.

Answer 2

Answer:

Like Direct and  Indirect(Inverse) Unitary Methord, Direct and Indirect(Inverse) Proportion stands for same. Direct Proportion means when both mean and extreme increases or decreases at the same time. In Indirect(Inverse) Proportion, when mean or extreme increases or decreases the other becomes opposite(if mean or extreme increases other decreases or if mean or extreme decreases the other increases).
