A true proportion is when two ratios are equal to one another. To prove this, you need to find the cross products of the ratios and see if they are equal. An example of a true proportion are the ratios 1/2 and 5/10, if you take the cross product the result is 2 x 5 = 1 x 10, which are equal.

What value of x will make this proportion true?

To determine the value of x that makes the proportion true, you need to set up the equation based on the given proportion. For example, if the proportion is a/b = c/d, you can cross-multiply to get ad = bc. Then, solve for x by isolating it on one side of the equation. If you provide the specific proportion, I can help you find the value of x.
