In the table below, the numbers in the first row are proportional to the corresponding numbers in the second row. What is the value of 𝑥?

So again, the numbers in the first row are proportional to the corresponding numbers in the second row. Therefore, three is to four as 𝑥 is to six.

And we can solve by cross multiplying. Three times six is 18 and four times 𝑥 is four 𝑥. So to solve for 𝑥, we divide both sides by four. The fours cancel and then 18 divided by four is 4.5. So the value of 𝑥 is 4.5.
