a, Ta có:
`17/30 = (17.3)/(30.3) = 51/90`
Vì ` 51/90 > 51/92 `
Nên `17/30 > 51/90`
b, Ta có:
`(-3)/5 = (-3 . 3)/(5.3) = (-9)/15`
Vì `-9/15 < -9/23`
Vậy `-3/5 < -9/23`
c, Ta có:
`159/23 > 1`
`615/724 < 1`
Nên `159/23 > 615/724`
`a)`
`17/30 = 51/90`
`Do 51/90 > 51/91`
`⇒ 17/30 > 51/91`
`b)`
`-3/5 = -9/15`
`Do -9/15 < -9/23`
`⇒ -3/5 < -9/23`
`c)`
`⇒ 159/23 > 615/724`
