The value of the constant of variation is 1/8 if the quantity m varies jointly with p and r when p is 2 and r is 4, m is 1.

What is directly proportional?

It is defined as the relationship between two quantity as the one quantity increases the other quantity also increases and vice versa.

We have a quantity m varies jointly with p and r.

Mathematically,

m ∝ p×r

After removing the proportional sign, a constant of proportionality encountered.

Let's c is the constant.

m = c(p×r)

If p = 2, r = 4, and m = 1

1 = c(2×4)

1 = 8c

c = 1/8

Thus, the value of the constant of variation is 1/8 if the quantity m varies jointly with p and r when p is 2 and r is 4, m is 1.
