Question

Vă rog frumos e urgent , dau coroană !​

Answer 1

A = 9/7 × 1/3 = 9 / 21 = 3/7

B = 9/1 × 7/(-3) = (-21)

C = (-28)/27 × - 9/12 = - 4/3

E = - 62/3 × 4/62 = - 4/3

F = 14/10 × 21/10 = 7/10 × 21/5 = 147/50

G = 17/15 × -113/900 = - 1921/13500

Answer 2

Răspuns:

A = 9/7 x 1/3 = 9 / 21 = 3/7

B = 9/1 7/(-3) = (-21)

C = (-28)/27 x - 9/12 = - 4/3

E = - 62/3 x 4/62 = - 4/3

F = 14/10 x 21/10 = 7/10 x 21/5 = 147/50

G = 17/15 -113/900 = - 1921/13500
