g, 23 : 8 + 35 : 8 − 10 : 8
= ( 23 + 35 − 10 ) : 8
= 48 : 8
= 6
h, 94 : 11 − 15 : 11 + 20 : 11
= ( 94 − 15 + 20 ) : 11
= 99 : 11
= 9
i, 37.138 − 38.37
= 37. ( 138 − 38 )
= 37. 100
= 3700
k, (77.45.24) : (8.9.11 )
= ( 77 : 11 ). ( 45 : 9 ). ( 24 : 8 )
= 7.5.3
= 105
l, ( 25 + 3.75 − 250 ) : ( 2014.2015.2016 + 2017.2018.2019 )
= ( 25 + 225 − 250 ) : ( 2014.2015.2016 + 2017.2018.2019 )
= ( 250 − 250 ) : ( 2014.2015.2016 + 2017.2018.2019 )
= 0 : ( 2014.2015.2016 + 2017.2018.2019 )

Đáp án:
mik làm 1 nửa nhé
Giải thích các bước giải:
`g) 23:8+35:8-10:8`
`=(23+35-10)/8=48/8=6`
`h) 94:11-15:11+20:11`
`=(94-15+20)/11=99/11=9`
`i) 37.138-38.37`
`=37*(138-38)=37*100=3700`
