**Solve the resulting equation**: The 50 on the left side cancels with the factors of 10 and 5 in the denominator. That results in: > $$\displaystyle \frac{3}{10}\cdot\frac{2}{5}\cdot50 = \frac{3}{5}\cdot 2x$$ > $$\displaystyle 6 = \frac{6x}{5}$$ Multiplying by 5 and dividing by 6 gives $$5 = x$$. That is, of course 5%.
Incorrect. [[snippet]] Your equation should look like this: $$\displaystyle\frac{30}{100}\cdot\frac{40}{100}\cdot 50 = \frac{60}{100}\cdot\frac{x}{100} \cdot 200$$ The rest is reducing and combining fractions.

Correct. [[snippet]] Translate: Use the percent language to translate the question, "Thirty percent of forty percent of fifty is sixty percent of what percent of two hundred". > $$\displaystyle 30\% \mbox{ of } 40\% \mbox{ of } 50 = 60\% \mbox{ of } x\% \mbox{ of }200$$ > $$\displaystyle\frac{30}{100}\cdot\frac{40}{100}\cdot 50 = \frac{60}{100}\cdot\frac{x}{100} \cdot 200$$ Reduce the fractions: When you reduce the fraction, you get $$\frac{30}{100} = \frac{3}{10}$$, $$\frac{40}{100} = \frac{2}{5}$$, $$\frac{60}{100} = \frac{3}{5}$$. On the right side, the 200 reduces with the 100 in the denominator to give 2. > $$\displaystyle \frac{3}{10}\cdot\frac{2}{5}\cdot50 = \frac{3}{5}\cdot 2x$$
