Question

 If X is inversely proportional to Y and when X is 5,Y will be 8. What will be the value of Y when X is 8 ​

Answer 1

Step-by-step explanation:

y = a*(1/x)

Where a is the coefficient of proportionality.

It follows that:

a = x*y

Substituting the known values gives

a = 4*8 = 32

if x = 5 now , y = 32÷x = 32÷8 = 4
