Question

Direct and inversse proprotion​

Answer 1

Step-by-step explanation:

When two quantities x and yare in direct proportion (or vary directly), they are written as x ∝ y. Symbol “∝” stands for 'is proportional to'. When two quantities x and y are in inverse proportion (or vary inversely) they are written as x ∝ 1 y .

Answer 2

Answer:

A direct and inverse proportion are used to show how the quantities and amount are related to each other. They are also mentioned as directly proportional or inversely proportional. The symbol used to denote the proportionality is’∝’. For example, if we say, a is proportional to b, then it is represented as ‘a∝b’ and if we say, a is inversely proportional to b, then it is denoted as ‘a∝1/b’. These relations are governed by some proportionality rules. Now in both cases, the value of ‘a’ changes in terms of ‘b’ or when the value of ‘b’ changes, the value of ‘a’ also get changed. The change in both values is equated with a constant of proportionality.
