To divide a line segment AB in the ratio 5:7, first a ray AX is drawn, so that BAX is an acute angle and then at equal distances points are marked on the ray AX such that the minimum number of these points is

Given, a line segment AB in the ratio 5:7


A:B = 5:7


Now,


Draw a ray AX which makes an acute angle BAX, then mark A+B points at equal distance. And, here, A=5 and B=7



Hence, minimum number of these points


= A+B


= 5+7


=12
