To solve this problem, you can set up a proportion. 60/300 is equal to 20/100 because to go from 300 to 100 you divide by 3. So if you divide 60 by 3, it's 20.
We are going to divide \(\frac{60}{300}\) by 3. \(\\ \frac{60:3}{300:3}= \frac{20}{100} \\\) Therefore, your answer is \(\boxed{ \frac{20}{100}}\) Hoped I helped. :)
