Answer 1

$\frac{4}{8} \: \: \: \: \frac{x}{16} \\ \\ by \: common \: sense \: the \: simpler \: form \: will\\ \: be \frac{1}{2} \\ \\ \\ so \: x = 8$

Answer 2

Answer:

=> The value of x will be 8.

Step-by-step explanation:

In context to the question asked,

We have to find the value of x,

It is given that,

$4:8::x:16$

In the form of a fraction, it is written as:

$=> \frac{4}{8}=\frac{x}{16}$

Now, by using cross multiplication:

=> 8 $\times$ $x$ = 4

Multiplying the numbers,

=> 8$x$ = 4 $\times$ 16

=> 8$x$ = 64

Divide both sides by 8, we get

=> $x = 8$

Hence, the required value of x is 8.
