Solve the proportion 4/9 = x/27 for x.

Explanation:
You're working with a proportion, so the two fractions are equal. Use cross-multiplication: 4 times 27 equals 9 times x. That gives 108 = 9x, so x = 108/9 = 12. You can also see it by scaling the right side: x equals 27 times the fraction 4/9, which is 27*(4/9) = 12. Substituting back shows 12/27 simplifies to 4/9, confirming the solution.
