order these from least to greatest

0.67, 9/10,0,-0.11

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

-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.

To order these numbers from least to greatest, you need to compare them. Let's break it down step by step:

1. Convert the fraction 9/10 to decimal form: To do this, divide the numerator (9) by the denominator (10). The result is 0.9.

Now that we have all the numbers in decimal form, we can order them from least to greatest:

-0.11, 0, 0.67, 0.9

So, the numbers from least to greatest are: -0.11, 0, 0.67, and 0.9.
