Answer: The line segment can be divided into 12 equal sections.
Step-by-step explanation: We are given to find the number of equal sections that divide a directed line segment if it is to be partitioned with a 5 : 7 ratio.
We know that
if a line directed line segment is partitioned in the ratio a : b, then we can divide the line segment in (a + b) equal sections.
So, the number of equal sections in which the given line segment can be divided is given by

Thus, the line segment can be divided into 12 equal sections.
