If p , q , r denotes the side of the triangle ,then the below expression will always lies between?
$\left(\frac{p}{q+r}\right) + \left(\frac{r}{q+p}\right) + \left(\frac{q}{p+r}\right) $
I tried to solve it by using the property that sum of length of 2 sides of triangle is always greater than 3rd side. So
p+q > r
q+r > p
r+q >p
So the expression should be less than 3.
But the answer in the book is : Range : 1.5 to 2. Thanks in advance.
