Answer: [tex]\frac{219}{100}[/tex]
======================================================
Explanation:
Think of [tex]2.19[/tex] as [tex]\frac{2.19}{1}[/tex] or [tex]\frac{2.19}{1.00}[/tex]
This works because dividing anything over 1 does not change the original number.
Then we can move the decimal point two spots to the right for each number
Therefore, [tex]2.19 = \frac{219}{100}[/tex]
