Answer:
Step-by-step explanation:
A rational number has the form
← where a and b are integers
3.12 = 
← divide numerator/denominator by 4, thus
3.12 = ← in simplest form
The area was originally 3*5, or 15 cm^2.
When the sides were enlarged, they were all multiplied by 3. The new sides are 3*3, or 9, and 5*3, or 15.
The new area is 9*15, or 135 cm^2.
If you divide 135, the new area, by 15, the original area, you get 9. So, the area increased by a factor of 9.
The zeros are 5, and -1/9. The second option is correct. Hope my work helps!
