Bonjour,
A=1/3×-4/5
1*-4 = -4
3* 5 = 15
=> -4/15
B=-8/3×3/4×5/7
= -24/ 12 * 5/7
= -2 * 5/7
= -10/7
C=5/3/4
= 5*4/3
= 20/3
D=4/9/(-1/4)
= 4/9 * -4
= -16/9
E=9/10/5/11
= 9/10 * 11/5
= 99/50

Bonjour,
A = 1/3 * -4/5
= -4/15
= -0,26
B = -8/3 * 3/4 * 5/7
= -8 * 1/4 * 5/7
= -2 * 5/7
= -10/7
C = 5 ÷ 3/4
= 5 * 4/3
= 20/3
D = 4/9 ÷ (-1/4)
= -4/9 * 4
= -16/9
E = 9/10 ÷ 5/11
= 9/10 * 11/5
= 99/50
