Explanation:
I'm not sure if I understood what the problem is asking for and if the numbers behind 3 are answer choices but the answer would be 21.
3's times table:

![3*7=21](https://img.qammunity.org/2023/formulas/mathematics/middle-school/hbmnwjdrlqcvk7zh025cy3xul4rsu6yfmn.png)
Since 3 times 7 equals 21 the following equations involving division with the numbers 3, 7, and 21 would be:
Hope this helps
