Answer 1

Răspuns:

Explicație pas cu pas:

a)2/3 : 1/6 = 2/3 x 6/1 = 2 x 2 = 4(simplificare 3 si 6 prin 3)

b)7/6 : 21/22 = 7/6 x 22/21 = 1/3 x 11/3 = 11/9

c)4 : 2/3 = 4 x 3/2 = 2 x 3/1 = 6

d)7/8 : 3 = 7/8 x 1/3 = 7/24

e)13/6 : 13/3 = 13/6 x 3/13 = 1/2 x 1/1 = 1/2

f)1/8 : 11/5 = 1/8 x 5/11 = 5/88

g)5 : 1/6 : 3/4 = 5 x 6 x 4/3 = 5 x 2 x 4 = 40

h)25/8 : 11/5 : 5/4 = 25/8 x 5/11 x 4/5 = 5/2 x 5/11 x 1 = 25/22

i)16/3:(5/2:15/4) = 16/3 : (5/2 x 4/15) = 16/3 : (1/1 x 2/3) = 16/3 : 2/3 =

16/3 x 3/2 = 8.
