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

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

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
