Đáp án:
a) `-5/6`
b) `-7333/2310`
Giải thích các bước giải:
a)
`11/3-14/3:16/9-10/3:16/9`
`= 11/3 - 14/3 . 9/16 - 10/3 . 9/16`
`= - 9/16 . ( 14/3 + 10/3 ) + 11/3`
`= - 9/16 . 8 + 11/3 = -9/2 + 11/3`
`= -27/6 + 22/6 = -5/6`
b)
`(-1.5).(1+2/3)+1,4 . 15/49-(4/5+2/3:11/5)`
`= (-3/2) . 5/3 + 7/5 . 15/49 - ( 4/5 + 2/3 . 5/11 )`
`= -5/2 + 3/7 - ( 4/5 + 10/33 )`
`= -5/2 + 3/7 - 182/165 = -7333/2310`
