How to approach this question

Recall the definition of inverse proportionality. If X is inversely proportional to Y, it can be written as X ∝ 1/Y. This means that X is directly proportional to the reciprocal of Y. Examine the given options to find the one that matches this definition.

Full Answer

B.X is directly proportional to 1/Y✓ Correct

The statement "X is inversely proportional to Y" is written mathematically as: X ∝ 1/Y This can be turned into an equation: X = k/Y, where k is the constant of proportionality. The expression "X ∝ 1/Y" can be read as "X is directly proportional to 1/Y". Therefore, the correct statement is that X is directly proportional to 1/Y.
