Question

Solve for x. 3:12 = x:16 9/4 4 64

Answer 1

Answer: The required value of x is 4.

Step-by-step explanation: We are given to solve the following equation for the value of x :

`3:12=x:16~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

We know that

`a:b=(a)/(b).`

So, from equation (i), we get

`3:12=x:16\\\\\\\Rightarrow (3)/(12)=(x)/(16)\\\\\\\Rightarrow (1)/(4)=(x)/(16)\\\\\\\Rightarrow x=(16)/(4)\\\\\Rightarrow x=4.`

Thus, the required value of x is 4.

Answer 2

You have
3/12 = x/16
Multiply by 16
16*(3/12) = x = 4

x = 4
