The third fin is the answer.
I’m pretty sure I did my math right, hope this helps.
I think answer should be d. Please give me brainlest let me know if it’s correct thanks bye
It's when we break a number apart. Like as if we take 3,864. And we take each number and put it in a area of the number.
3=Thousands.
8=Hundreds.
6=Tens.
4=Ones.
Fairly simple and easy.
