Bonjour;
7). Effectuer les calculs suivants.
A= 3/4 : 2/7
=3/4*7/2
= 21/8
B= 1/3 : 1/4 =
= 1/3*4
=4/3
C= 14 : 2 =
=7
D= 15/2 : 5 =
= 15/2 *1/5
= 15/10 = 3/2
8). Effectuer les calculs suivants.
E= -15/2 : (-7/2) =
-15/2 *-2/7
= 30/14= 15/7
F= 3/10 : 4/10 =
3/10*10/4 = 30/40
= 3/4
G= 13/14 : (-3) =
=13/14* (-1/3)
= -13/42
H = -5 : 15/4 =
= -5*4/15
= -20/15
= -4/3
