1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 4=9x$
2. Which gives: $8=9x$
3. Divide both sides by 9 to isolate x: $\frac{8}{9}=\frac{9x}{9}$
4. Which gives the result: $\frac{8}{9}=x$

Thus, 2/9 of 4 is equal to 8/9 (or 0.88888888888889 in its decimal form).
