I can not solve this problem:

3/4 =5/x

multiply both sides by 4x

3/4 * 4x = 5/x * 4x

or

3x = 20

x = 20/3

which is 6 2/3

I never posted this, and it says I did, what the heck? Is their another Kaylee? Anyway, 'me' the correct answer is this I believe; if you are doing proportions. 6.67. 4 x 5 = 20. 20/3 = 6.6666666666666666666666666666666666666666666666666666666666666666666666666666666666666666667. Put it in the simplest form, 6.67 or 6.8
