​All numbers to the RIGHT of zero are positive.

​

​All numbers to the LEFT of zero are negative.

Example

Identify the dots on the number line.

Multiple Choice

Put the rational numbers in order from least to greatest.
-1, -1.1, -1.5, -1.15, -0.5

• ^{-1.5, -1.15, -1.1, -1, -0.5}
• ^{-1.1, -1, -1.5, -1.15, -0.5}
• ^{-0.5, -1.1, -1, -1.5, -1.15}

​Example

Multiple Choice

Order the numbers from greatest to least. $$0,4,-4\frac{1}{5}\ ,\ -4\frac{1}{2},\ -4$$  

• $$-4\frac{1}{2},\ -4\frac{1}{5}\ ,\ -4\ ,\ 4\ ,\ 0$$  

• $$0\ ,\ \ 4\ ,\ -4\ ,\ -4\frac{1}{5}\ ,\ -4\frac{1}{2}$$  

• $$4\ ,\ 0\ ,\ -4\ ,\ -4\frac{1}{5}\ ,\ -4\frac{1}{2}$$  

• $$4\ ,\ 0\ ,\ -4,\ -4\frac{1}{2}\ ,\ -4\frac{1}{5}$$
