-22/45>-51/103

-22/45>-51/103

\(\frac{-22}{45}\)và\(\frac{-51}{103}\)

ta thấy;

\(\frac{-22}{45}>\frac{-51}{45}>\frac{-51}{103}\Rightarrow\frac{-22}{45}>\frac{-51}{103}\)

vậy...

TA CÓ : 22/45<22/44=1/2=51/102<51/101=>22/45<51/101=>-22/45=>-51/101

... sai lỗi cơ bản

-22/45>-51/103

2A=-44/45=>2A-1/45=-45/45=-1.

2B=-102/103=>2B-1/103=-103/103=-1.

=>2A-1/45=2B-1/103.

Mà 1/45>1/103.

=>2A>2B=>A>B.

k nha có j kb vs mk nha

ta chọn phân số trung gian là \(\frac{-51}{45}\)

ta thấy \(\frac{-22}{45}>-\frac{51}{45}\) mà \(-\frac{51}{45}>-\frac{51}{103}\) nên \(-\frac{22}{45}>-\frac{51}{45}>-\frac{51}{103}\)\(\Rightarrow-\frac{22}{45}>-\frac{51}{103}\)

vậy...

tao giai duoc roi lu ngu a

\(\frac{-22}{45}>-\frac{51}{103}\)

K nha

kb nha

-22/45 >-51/103

\(-\frac{22}{45}>-\frac{51}{103}\)

−2245>−51103

Ta có -22/45 = -0.4(8)

            -51/103= -0.3923...

Mà -0.4(8) < -03923....

Vậy -22/45 < -51/103

-22/45>-51/103

Xét tích :

(-22) . 101 = -2222

(-51) . 45 = -2295

Vì -2222 > -2295 => (-22) . 101 > (-51) . 45

=> \(\dfrac{-22}{45}>\dfrac{-51}{101}\)

Vậy \(\dfrac{-22}{45}>\dfrac{-51}{101}\)

Cách khác:

Ta có: \(-\dfrac{22}{45}>-\dfrac{1}{2}\\ -\dfrac{51}{101}< -\dfrac{1}{2}\\ =>-\dfrac{22}{45}>-\dfrac{51}{101}\left(t.c-bắc-cầu\right)\)

\(\dfrac{-22}{45}\)>\(\dfrac{-51}{101}\)
