Question

what is 0.17 smaller or bigger than 0.165

Answer 1

0.17 is smaller than 0.165 because 0.165 goes all the way to thousandths. 
0.17= seventeen hundredths.
0.165= one hundred sixty-five thousandths.
Of course, 0.165 is bigger.

Answer 2

Then answer is 0.17<0.165 because of course it is a really big number and 0.17 is a small number compared to 0.165, 0.165 is 0.148 more than 0.17 so of course your answer is 0.17<0.165
