solve for x 8/x = 12/30

Solve For X 8/x = 12/30

Answers

Answer 1

Answer:

x = 20

Step-by-step explanation:

We can cross multiply to isolate x

[tex]\frac{8}{12}[/tex] = [tex]\frac{x}{30}[/tex]

multiply 30 from both sides

[tex]\frac{30*8}{12}[/tex] = [tex]x[/tex]

simplify and we get

[tex]20 = x[/tex]

Answer 2

x = 20,  After solving the question the value of X is 20. Therefore option B is correct.

What is Cross Multiplication?

The process of multiplying integers in the shape of a fraction is called cross multiplication. Cross multiplying, also known as cross multiplication, is the process of multiplying the numerator of one fraction by the denominator of the other fraction on the other side of an equal sign. Cross multiplication is a method for comparing fractions.

Detailed explanation:

Cross multiplying allows us to isolate x.

30 divided by both sides

8/x =12/30

= 12x = 30×8

= x = 240/12

= x = 20
