Answer 1

EF is 1/4 of the length of the line segment CD. If CD=4 cm, then EF = 1cm

Step-by-step explanation:

Let x be the length of CD.

It is given that length of a line segment AB is 2/3 of the length of the line segment CD.

$AB=\frac{2}{3} \: CD$

$AB=\frac{2}{3}xAB$

The length of another line segment EF is 3/8 of the length of the line segment AB.

$EF=\frac{3}{8}AB=\frac{3}{8}(\frac{2}{3}x)=\frac{1}{4}$

$EF=\frac{1}{4}CD$

Therefore, EF is 1/4 of the length of the line segment CD.

It is given that CD=4 cm,

$EF=\frac{1}{4}$

(4)=1

If CD=4 cm, then EF = 1cm.
