Answer:

3

Step-by-step explanation:

1:3::x:9

1/3=x/9

3x=9

x=9/3

x=3

Answer 2

Answer:

=> The value of x is 3.

Step-by-step explanation:

Given that:-

$1 : 3 :: x :9$

To find:- The value of x,

The given ratio is written as:-

=> $\frac{1}{3}=\frac{x}{9}$

Now by using the method of cross-multiplication, we get

=> 3 $\times$ $x$ = 9 $\times$ 1

Simplifying it further, we get

=> 3$x$ = 9

Divide both sides by $3$, we get

=> $x$ = 3

Hence, the required solution is 3.
