Sagot :

Bjr,

280 = 140 * 2 = 70 * 2 * 2 = 35 * 2 * 2 * 2 = 7 * 5 * 2 * 2 * 2

448 = 56 * 8 = 8 * 7 * 8 = 2 * 2 * 2 * 7 * 2 * 2 * 2

280/448 = (7 * 5 * 2 * 2 * 2)/(2 * 2 * 2 * 7 * 2 * 2 * 2) = 5/8

Réponse:

280 = 2×140 = 2×2×70= 2×2×2×35= 2×2×2×5×7

448 = 2×224 = 2×2×112 = 2×2×2×56 = 2×2×2×2×28= 2×2×2×2×2×14= 2×2×2×2×2×2×7

aprzs c'est 5 sur 8

Bonne soirée
