Answer 2

Ratios compare two numbers, usually by dividing them. If we are comparing one data point (P) to another data point (Q), The formula would be P/Q.

That means we are dividing information P by information Q.

Let consider the missing number = x

105:150=39: x

⇒ $\frac{105}{150}$ = $\frac{39}{x}$

⇒ 150 × 39 = 105 x

⇒105 x = 5850

 ⇒x = $\frac{5850}{105}$ = 55.71

Hence the missing number will be 55.71 = (aprox) 56

Ans :- The missing number will be 55.71 = (aprox) 56, and (105:150::39: 56 ) will be number analogy​.
