Explications étape par étape
Bonjour,
34/51 = (2 x 17)/(3 x 17)
simplifier par 17
34/51 = 2/3
45/72 = (5 x 9)/(9 x 8)
simplifier par 9
45/72 = 5/8
96/64 = (4 x 4 x 2 x 3)/(4 x 4 x 2 x 2)
simplifier par (4 x 4 x 2) soit 32
96/64 = 3/2
57/38 = (3 x 19)/(19 x 2)
simplifier par 19
57/38 = 3/2
exercice 19
15/25 = (5 x 3)/(5 x 5) = 3/5
32/24 = (8 x 4)/(8 x 3) = 4/3
111/74 = (37 x 3)/(37 x 2) = 3/2
4/22 = (2 x 2)/(2 x 11) = 2/11
18/27 = (2 x 9)/(3 x 9) = 2/3
42/35 = (6 x 7)/(5 x 7) = 6/5
14/24 = (2 x 7)/(2 x 12) = 7/12
50/45 = (5 x 10)/(5 x 9) = 10/9
