Bonjour pouvez m'aider svp voilà l'énoncé Calculer en décomposant chacun des facteurs si cela est possible : F = 81/56 * 7/9 G = 40/27 * - 18/35 H = 28/- 15 * 6

Bonsoir,

F = 81/56 * 7/9

9/56 *7

= 9/8

G = 40/27 * - 18/35

= 8/27* -18/7 =

= -16/21

H = 28/- 15 * 60/- 63

= -4/15*-60/9

= 4*4/9

= 16/9

I = - 16/32 * - 33/- 36​

= -1/2 *-11/12

= 11/24

Bonsoir,

Calculer :

F = 81/56 × 7/9

F = 9/56 × 7

F = 9/8

G = 40/27 × -18/35

G = -40/27 × 18/35

G = -8/27 × 18/7

G = -8/3 × 2/7

G = -16/21

H = 28/-15 × 60/-63

H = 28/15 × 60/63

H = 28 × 4/63

H = 4 × 4/9

H = 16/9

I = -16/32 × -33/36

I = 16/32 × 33/36

I = 1/2 × 33/36

I = 1/2 × 11/12

I = 11/24

/ = fraction.

Bonne soirée.
