[-23]+13+[-17]+5

= -23 + 13 - 17 + 5

= -22

[-554]+[94+[-554]+[-14] ]

= -554 + 94 - 554 - 14

= -1208

573+[184+[-573]+[-34] ]

= 573 + 184 - 573 - 34

= 150

469+[-219]+37+[-23]

= 469 - 219 + 37 - 23

= 264

M = 89 + 94 + 99 + ... + 554 + 559 ( cách đều 5 đơn vị )

M có số số hạng là : ( 559 - 89 ) : 5 + 1 = 95 số

M = ( 89 + 559 ) x 95 : 2 = 30780

N = 1032 + 1029 + 1026 + ... + 600 + 597 ( cách đều 3 đơn vị )

N có số số hạng là : ( 1032 - 597 ) : 3 + 1 = 146 số 

N = ( 1032 + 597 ) x 146 : 2 = 118917

M=(89+559)+(94+554)+.....+(322+326)

M=648+648+....+648(95 cặp)

M=648*95

M=61560

bn nào có kết quả giống m thì ủng hộ nhé

M = 89 + 94 + 99 + ... + 554 + 559

M có số số hạng là: (559 - 89 ) : 5 + 1 = 95( số hạng )

M = (89 + 559) x 95 = 30780

N = 1032 + 1029 + 1026 + ... + 600 + 597

N có  số số hạng là : (1032 - 597 ) : 3 + 1 = 146 ( số hạng )

N = ( 597 + 1032 ) x 146 : 2 = 118917

=77/99-42/99

=35/99

\(\dfrac{77}{99}-\dfrac{28}{99}-\dfrac{14}{99}=\dfrac{77-28-14}{99}=\dfrac{35}{99}\)

Trả lời

Ý 1

-63/36   với     636363/363636

-63/36    <       636363/363636

Ý nghĩa 2:

63/36    =     63/36

Vì   636363/363636 rút gọn cho 10101 thành phân số 63/36

-145/554   với    554/454

-145/554 <    554/454

Phân số âm bé hơn phân số dương

Ý nghĩa 2:

   145/554       <     554/454

Vì 145/554 < 1 còn 554/454 > 1

Học tốt !

đáp án : 63\36  = 636363\363636 vì 636363\363636 : 10101 = 63\36

đáp án : 145\554 < 554\454 vì 145\554 bé hơn 1 còn 554\454 thì lớn hơn 1

72/99 -28/99 -14/99

= 1/99. ( 72-28-14)

= 1/99 . 30

=30/99= 10/33

=600
