\(\dfrac{-22}{45}=-\dfrac{2266}{45.103}>-\dfrac{2295}{45.103}=-\dfrac{51}{103}\)

Ta có: \(\dfrac{-22}{45}=\dfrac{-22\cdot103}{45\cdot103}=\dfrac{-2266}{4635}\)

\(\dfrac{-51}{103}=\dfrac{-51\cdot45}{103\cdot45}=\dfrac{-2295}{4635}\)

mà -2266>-2295

nên \(\dfrac{-22}{45}>\dfrac{-51}{103}\)

Đồng tiên bạn quy đồng, rồi so sánh nhé

-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

dấu > nha bn

~~ tk mk đi ~

Ai tk mk mk tk lại ~~

Kb vs mk nha m.n, ai kb mk tk 3 cái lun ~~

n_n

Ta có: Phân số trung gian của -\(\frac{-22}{45}\)và \(\frac{-51}{103}\)là\(\frac{-22}{103}\)

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

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

\(\frac{-22}{45}\)<\(\frac{-22}{103}\)
