9 students chose duck
Step-by-step explanation:
The question says "6 <em><u>more</u></em> students chose duck <em><u>than</u></em> chose penguin"
This means that you would add 6 to the number that chose penguin, which is 3.
6 + 3 = 9
52 divided by 130 would be 0.4 so if you need it in percent then it would be 4%.
