Hi Sasha! I understand this math is hard,but I'm here to help. 9 goes on top of 14!
If we put 14 on top of 9 it would be an inproper fraction,that's when a fraction is not very easy to work with. Now, we could do 9÷14. :)
Hope dis helps!

This is false because when you multiply a number by 10, you simply move the decimal place one to the right. In this case, when we multiply 0.02 by 10, we get .2. Had we multiplied 0.02 by 100, we would have gotten 2.
