Question

If x: 12 :: 3 : 4, find x​

Answer 1

Step-by-step explanation:

x:12=3:4

“:” Sign is a sign of division. So then you replace “:” with “/”(another sign of division/fraction)

So, x/12=3/4

In division, the opposite signs (i.e. 12 and 3 and x and 4) go for multiplication.

Hence, x/12=3/4

4x = 12x3

Then it becomes a simple “x” equation and you find the value of x

4x= 36

x=36/4

X=9

Which is your answer!

Answer 2

Step-by-step explanation:

$given$

x:12=3:4

$to \: find$

the value of x

So,

x:12:3:4

x : 12=3:4

x/12=3/4

4x=12×3

4x=36

x=36/4

x=9

$ans \: x = 9$
