Sagot :
Bonjour,
36/10 = (18 * 2)(5 * 2) = 18/5
36/72 = (36 * 1)/(36 * 2) = 1/2
35/30 = (7 * 5)/(6 * 5) = 7/6
111/63 = (37 * 3)/(21 * 3) = 37/21

Bonjour
Explications étape par étape
36/10 =
(22 × 32)/(2 × 5) =
((22 × 32) : 2) / ((2 × 5) : 2) =
(2 × 32)/5 =
18/5
36/72 =
(22 × 32)/(23 × 32) =
((22 × 32) : (22 × 32)) / ((23 × 32) : (22 × 32)) =
1/2
35/30 =
(5 × 7)/(2 × 3 × 5) =
((5 × 7) : 5) / ((2 × 3 × 5) : 5) =
7/(2 × 3) =
7/6
111/63 =
(3 × 37)/(32 × 7) =
((3 × 37) : 3) / ((32 × 7) : 3) =
37/(3 × 7) =
37/21
Bonne journée
