Question

If 3/4 and 12/r are equivalent, what is the value of x?

Answer 1

r = 16

Step-by-step explanation:

I think you mean r not x.

3/4 times ? = 12/r

3/4 times 4 = 12/r

4 times 4 = 16

3/4 times 4 = 12/16

Answer 2

The value of x is 16.

Step-by-step explanation:

Given data:

3/4 = 12/r

The value of x = ?

Solution:

3/4 = 12/r

By multiplying 4 on both sides of equation:

= 3/4 × 4 = 12/r × 4

= 3 = 48/r

By cross multiplication:

= 3r = 48

By dividing 3 on both sides:

= 3r/3 = 48/3

= r = 16

The value of x = 16

Step-by-step explanation:

Here the value of x means the value of r. Because in equation r is unknown and in general mathematics x means an unknown value.

So by simplifying and solving the equation, r is equal to 16. And consequently x is equal to 16.
