Answer 2

The value of missing number (?) is equal to 1.

Step-by-step explanation:

We have,

2 : 0.5 : : 4 : ?

To find, the value of missing number (?) = ?

We know that,

a : b : : c : d

Product of means = Product of extremes

a × d = b × c

∴ 2 × ? = 0.5 × 4

⇒ 2 × ? = 2

⇒ ?  =  $\dfrac{2}{2}$

⇒ ?  = 1

∴ The value of missing number (?) = 1

Thus, the  value of missing number (?) is equal to 1.
