We are given that 30% of 30 questions were answered right. To know the number of questions that were right we need to multiply the number of the question by 30%, that is 30/100, like this:
![30*(30)/(100)](https://img.qammunity.org/2023/formulas/mathematics/college/yz3fgvbzri8q3dzjxdhw7v7ijkz7krh3p2.png)
Solving the operations we get:
![30*(30)/(100)=9](https://img.qammunity.org/2023/formulas/mathematics/college/x6yf2aloaghx3z58vpsgpcwv1xqupl3y39.png)
Therefore, 9 questions were answered right.
