Answer 2

Here is your answer

Let the fourth proportional is x
so
13/3 : 39/4 = 17/2 : x
$\frac{13}{3} \times x = \frac{17}{2} \times \frac{39}{4} \\ x = \frac{17 \times 39 \times 3}{2 \times 4 \times 13} \\ x = \frac{17 \times 3 \times 3}{2 \times 4} \\ x = \frac{153}{8}$
Therefore the fourth proportional is
$= \frac{153}{8}$

Hope it helps you
