Answer:

hii ur answer is

Step-by-step explanation:

If x:12 = 3:4, what is the value of x?

Season to start anew.

See what you do here is that first you write down the question on the top

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!
