Va rog sa ma ajutați!!​

Answer 1

Răspuns:

Explicație pas cu pas:

a)

x = 5/9 : 4/3 = 5/9 * 3/4 = 5/12

b)

x = 3/8 : 5/2 = 3/8*2/5 = 3/20

c)

x = 8/5 : 6/7 = 8/5*7/6 = 28/15

d)

x = -4/15 : 8/27 = -4/15*27/8 = -9/10

e)

x = -15/4 : 25/8 = -15/4 * 8/25 = -6/5

f)

x = 2/9 : 4/3 = 2/9*3/4 = 1/6

Answer 2

4.

a) 4/3 X=5/9

X=5/9:4/3

X=5/9×3/4

X=15/36

Simplificam cu 3

X=5/12

b) 5/2 X=3/8

X=3/8:5/2

X=3/8×2/5

X=6/40

Simplificam cu 2

X=3/20

c) 6/7 X=8/5

X=8/5:6/7

X=8/5×7/6

X=56/30

Simplificam cu 2

X=28/15

d) 8/27 X=-4/15

X=-4/15:8/27

X=-4/15×27/8

X=-108/120

Simplificam cu 4

X=-27/30

e) 15/4=-25/8 X

X=15/4:(-25/8)

X=15/4×(-8/25)

X=-120/100

X=-1,2

f) -4/3X=-2/9

X=-2/9:(-4/3)

X=2/9×3/4

X=6/36

Simplificam cu 6

X=1/6
