Câu `1:`
`16/58 + (-3)/29 = 8/29 - 3/29 = 5/29`
Ta thấy :`5/29 < 6/29 (do\ 5<6)`
`=> 16/58 + (-3)/29 < 6/29`
Câu `2:`
`a)`
`7/12 + 1/24 = 14/24 + 1/24 = 25/24 > 1`
`1/2 < 2/2 = 1`
`=> 7/12 + 1/24> 1/2`
`b)`
`3/4 + (-1)/6 = 9/12 - 2/12 = 7/12 = 35/60`
`2/5 = 24/60`
Ta thấy : `35/60 > 24/60 (do\ 35>24)`
`=> 3/4 + (-1)/6 > 2/5`
