Question

order these from least to greatest
0.67, 9/10,0,-0.11

Answer 1

9/10 = 0.9

Negative numbers are smaller than zero and positive numbers, so -0.11 is the least.

Zero is less than the other positive numbers.

0.67 is less than 0.9

So,

-0.11 < 0 < 0.67 < 0.9

Answer 2

-0.11 < 0 < 0.67 < 0.9

This is correct. Negative numbers are indeed less than zero. Think of your check book, or of owing someone money when you're broke.
