Answer:
2:1
Step-by-step explanation:
use k:1 as ratio, and then apply the section formula.
let's use the x co-ordinate pf the point in between the other two which is=(3)
section formula says,
x=mx2 + nx1/(m+n)
m=k , n=1
substitute all the values,
3=5k+(-1)/(k+1)
take k+1 to left side,
3(k+1)=5k-1
3k+3=5k-1
5k-3k=3+1
2k=4
(÷2)
k=2
hence, the ratio = 2:1
