1.201
A
1.2
B
1.21
с
1.2
D

Answer:
C
Step-by-step explanation:
If you put zeros at the end of the decimals or look at the digits, it can really make it easier.
A=1.201
B=1.200
C= 1.210
D= 1.200
Now, you see that in the hundredths place for C that there's 1 while the others have 0? That's how you can solve it!
