Answer 2

Answer:

Step-by-step explanation:

You always invert the second number in a division question and then multiply. This one is a little different. It has three levels. What do you do about that?

$\frac{\frac{1}{9} }{\frac{2}{1} }$

Now you have a four level question which is handled the same way as all four level question.

Invert the bottom and multiply. Invert means turn upside down. So you turn the 2/1 upside down and you get 1/2

$\frac{1}{9}*\frac{1}{2}$

What you get is 1/18 The green box with the question mark is a 1.
