Understanding irrational numbers

Put these numbers in order from greatest to least.

In between what two integers is

 $\sqrt{77}$  

• 5 and 6

• 6 and 7

• 7 and 8

• 8 and 9

Order from least to greatest:
6.9, √37, √25,  $\frac{28}{4}$  

• 6.9, √37, √25,  $\frac{28}{4}$  

•  $\frac{28}{4}$  , 6.9, √37, √25, 

• √37, √25,  $\frac{28}{4}$  , 6.9

• √25, √37, 6.9,  $\frac{28}{4}$  

Put the given numbers in ascending order: -0.2, √3, -1.8, 2.9

• -1.8, -0.2, √3, 2.9

• 2.9, √3, -1.8, -0.2

• √3, -0.2, -1.8, 2.9

• -0.2, -1.8, √3, 2.9

Place the numbers in order from least to greatest
