Question

72: ___ : :108 : 192

What do I do?

Answer 1

Answer:

72 : 128 :: 108 : 192

Step-by-step explanation:

72 : ? :: 108 : 192  

Let the missing number be x.

⇒  $\frac{72}{x}$ = $\frac{108}{192}$

⇒  72 × 192 = 108 × (x)

⇒  13824 = 108x

⇒  x = 13824/108

⇒  x = 128

∴ x = 128

So, We get the ratio as 72 : 128 :: 108 : 192
