Cross Multiply- solving for x?

Question

I learned this so long ago and can't remember how to get x.

How would you solve doing cross multiplication:

6/x = 18/4

Answer 1

6/x = 18/4

Just cross multiply:

(x) (18) = (6) (4)

18x = 24

x = 24/18

Reduced to lowest term:

x = 4 / 3 -----> ans

Answer 2

not hard

To get rid of denominators, you must multiply both sides by both of them. That means 4x.

This has the result of "cross multiplying"

4x times 6/x = 4x times 18/4

so 24=18x

now divide to get rid of 18

24/18=x

simplify

4/3=x

1 1/3 = x

Answer 3

                6/x     = 18/4

                Cross Multiply

              X x 18  = 6 x 4

       Divides both sides by 18

       (X x 18)/18  =  (6 x 4)/18

                       X  =  24/18

  

                       X   = 4/3

    

Answer 4

6/x = 18/4

6 = X18/4

6 Divide by 18/4 = X

so X = 4/3

Answer 5

6/x=18/4

6 X 4 = 18 X x

24 = 18x

24/18 = x

Simplify it by dividing the numerator and denomintor by 6 which makes

4/3=x

= 1 1/3 =x

Answer 6

You would1st multiply 18 and 4, which is 72.

then u would divide both sides by 6, so u are left with x=12.
