Dear Student,
According to 1st statement we calculated ratio of distance between a and b.
similarly for a and c , and for b and c .
Now using the first two ratios, i.e( a :b ) and ( a:c) we calculated a:b:c
Now use ratio a:b:c and any other ratio like a:b or a:c or b:c and solve.

Thanks and Regards
