Question

Find the porportion 3/12 = 2/x

Answer 1

Explanation:

the answer to this question is 2/8, x is 8

in order to do this proportion, you have to

1.Cross multiply:

3 * x = 12 * 2

2.

Simplifying

3 * x = 12 * 2

3.

Multiply 12 * 2

3x = 24

4.

Solving

3x = 24

5.

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

6.

Divide each side by '3'.

x = 8

7.

Simplifying

x = 8

meaning that 3/12 = 2/8

Answer 2

x = 8

Explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. First, multiply 12 and x to both sides of the equation:

(3/12)(12)(x) = (2/x)(12)(x)

3 * x = 2 * 12

3x = 24

Isolate the variable, x. Divide 3 from both sides of the equation:

(3x)/3 = (24)/3

x = 24/3

x = 8

x = 8 is your answer.
