Answer 1

Heya!!
---------


=============================================================


♦Given Ratio is 3 : 4 : 7
--------------------------------


◾So let the Numbers be 3x , 4x and 7x respectively.


➰According to the given question:-
=================================

=> 3x • 4x • 7x = 18144

=> 84x³ = 18144

=> x³ = 18144/84

=> x³=216

=> x = 6
========


➡Numbers are =>>

↪3 (6 ) = 18 ✔

↪4 (6) = 24 ✔

↪7 (6) = 42 ✔


===========================================================

Answer 2

The three numbers are "18, 24 and 42".

Step-by-step explanation:

Let first number = 3x, second number = 4x and third number = 7x

To find, the numbers = ?

According to question,

$3x\times 4x\times 7x=18144$

⇒ $84x^{3} =18144$

⇒ $x^{3} =\dfrac{18144}{84} =216$

⇒ $x^{3} =6^{3}$

∴ $x=6$

First number = 3 × 6 = 18

Second number = 4 × 6 = 24 and

Third number = 7 × 6 = 42

Thus, the three numbers are "18, 24 and 42".
