7/24 + 5/8
= 7/24 + 15/24
= 22/24
= 11/12
3 - 17/4
= 12/4 - 17/4
= - 5/4
5/9 - 7/12
= 60/108 - 63/108
= - 3/108

Bonsoir
pour additionner ou soustraire des fractions, tu dois les mettre au même dénominareur commun
a) 7/24 + 5/8 = 7/24 + 15/24 = 22/24
tu simplifies par 2 = 11/12
b) 3 - 17/4 = 12/4 - 17/4 = - 5/4
c) 5/9 - 7/12 = 20/36 - 21/36 = - 1/36
