#### Answer

(a) $\overline{EC}$ is longer than $\overline{AE}$
(b) $\overline{DB}$ is longer than $\overline{CD}$
(c) $\overline{FB}$ is longer than $\overline{AF}$

#### Work Step by Step

(a) $\frac{AE}{AB} = \frac{EC}{BC}$
$\frac{AE}{6.7} = \frac{EC}{7.2}$
$AE = \frac{6.7}{7.2}~EC \lt EC$
(b) $\frac{CD}{AC} = \frac{DB}{AB}$
$\frac{CD}{5.3} = \frac{DB}{6.7}$
$CD = \frac{5.3}{6.7}~DB \lt DB$
(c) $\frac{AF}{AC} = \frac{FB}{BC}$
$\frac{AF}{5.3} = \frac{FB}{7.2}$
$AF = \frac{5.3}{7.2}~FB \lt FB$
