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.
<h3>What is directly proportional?</h3>
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.
