the variable Y is inversely proportional to variable X. if Y =0.4 when X = 2.5, find the value of the constant of proportionality

Answer 1

When two variables are inversely proportional, their product is constant. We can use this relationship to find the constant of proportionality in this problem.

Let k be the constant of proportionality. Then we have:

Y * X = k

We know that when Y = 0.4 and X = 2.5:

0.4 * 2.5 = k

k = 1

Therefore, the value of the constant of proportionality is 1.
