Given that,
Points A$(1/2,3/2)$ and B$(2,-5)$
Let’s consider the point P$(3/4,5/12)$ divide the line segment AB in the ratio k:$1$
As, we know that
P$(3/4,5/12)=(2k+1/2)/(k+1),(2k+3/2)/(k+1)$
Therefore, on equating the abscissa we get
$3/4=(2k+1/2)/(k+1)$
$3(k+1)=4(2k+1/2)$
$3k+3=8k+2$
$5k=1$
$k=1/5$
Hence, the ratio in which the point P$(3/4,5/12)$ divides is $1:5$
