If p,q and r are in proportion and q =17, r=289, find p.
Given:
p, q, r are in proportion.
q = 17 and r = 289.
To do:
We have to find the value of p.
Solution:
p, q and r are in proportion.
Therefore,
$\frac{q}{p}=\frac{r}{q}$
$p=\frac{q^2}{r}$
Substitute q, r values in the above equation,
$p=\frac{17^2}{289}$
$p=\frac{289}{289}$
$p = 1$
The value of p is 1.
