Question

Answer 1

a. <

b. =

c. >

Answer 2

\(x=\dfrac{-25}{35}=\dfrac{-5}{7}\)

\(y=\dfrac{444}{-777}=-\dfrac{4}{7}\)

-5 <  -4

=> x < y

Answer 3

`x = (-25)/35 = (-5)/7`

`y = 444/(-777) = 4/(-7)`

Mà : `-5 < -4`

`=> x < y`

_______________________________

`x = (-11)/5`

`y = (-11)/5`

Mà : `(-11)/5 = (-11)/5`

`=> x = y`

______________________________________

`x = 17/20`

`y = 0,75 = 3/4 = 15/20`

Mà : `17 > 15`

`=> x > y`
