Bonsoir pouvez me faire l'exercice 46 merci

Bonsoir,

a.
2/3 x 3/7 x 5/11
= 6/21 x 5/11
= 30/231
= 3 x 10 / 3 x 77
= 10/77

b. 
3/5 x 13/7 x 5/2
= 39/35 x 5/2
= 195/70
= 5 x 39 / 5 x 14
= 39/14

c. 
3/2 x 2/5 x 3/11
= 6/10 x 3/11
= 18/110
= 2 x 9 / 2 x 55
= 9/55

d.
6/5 x 1/14 x 7/3
= 6/70 x 7/3
= 42/210
= 42 x 1 / 42 x 5
= 1/5

e.
45/6 x 1/9 x 18/7
= 45/54 x 18/7
= 810/378
= 54 x 15 / 54 x 7
= 15/7

f.
6 x 1/88 x 11/12
= 6/88 x 11/12
 = 66/1056
= 66 x 1 / 66 x 16
= 1/16

g.
5,5/3 x 9/7,7
= 49,5/23,1
= 49,5 x 10 / 23,1 x 10
= 495/231
= 33 x 15 / 33 x 7
= 15/7

h.
6 x 2,8/3 x 5/0,7
= 16,8/3 x 5/0,7
= 84/2,1
= 84 x 10 / 2,1 x 10
= 840/210
= 210 x 4 / 210 x 1
= 4

i.
0,6 x 2/3,6
= 1,2/3,6
= 1,2 x 10 / 3,6 x 10
= 12/36
= 12 x 1 / 12 x 3
= 1/3

j.
17/12,5 x 2,5/1,7
= 42,5/21,25
= 42,5 x 100 / 21,25 x 100
= 4250/2125
= 2125 x 2 / 2125 x 1
= 2
