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

To solve this problem, you need to find the value of 'x' that makes the equation 3/4 = 5/x true.

To do this, you can cross-multiply the fractions. Cross-multiplying means multiplying the numerator of the first fraction by the denominator of the second fraction and vice versa. In this case, it would look like this:

3 * x = 4 * 5

Simplifying this equation, you get:

3x = 20

To isolate 'x' on one side of the equation, divide both sides of the equation by 3:

3x/3 = 20/3

Simplifying further:

x = 20/3

Therefore, the value of 'x' that satisfies the equation 3/4 = 5/x is x = 20/3 (or approximately 6.67).
