Answer 2

Value of x is 55.714,

105 : 150 :: 39 :  55.714

Step-by-step explanation:

105 : 150 :: 39 : ?

By the ratio and proportion,

105 : 150 :: 39 : X

Multiply first to 4th term and 2nd to third term,

We get,

$105 \times x = 150 \times 39$

$x = \frac{150\times 39}{105}$

$x = \frac{5850}{105}$

x = 55.714

Thus, we get,

105 : 150 :: 39 :  55.714
