Here is your answer
Let the fourth proportional is x
so
60 : 48 = 30 : x
$60 \times x = 48 \times 30 \\ x = \frac{48 \times 30}{60} \\ x = 24$
Therefore Fourth proportional is 24

Answer 2

Hey mate!!

here is your answer:
____________________

Let the fourth proportional to 60,48 and 30 be x.


therefore, 60:48:30:X

Product of means = Product of extremes

so, 48×30=60x

x= $\frac{48×30} {60}$

x=24 (after simplification)

hence, the fourth proportional to 60,48 and 30 is 24
