Answer 2

Răspuns:

Explicație pas cu pas:

a) = 11/5 : 3 = 11/5 x 1/3 = 11/15  = > 0,7(3)

b) = 11/5 : 1/6 = 11/5 x 6/1 = 66/5 = 13 intregi 1/5  = > 13,2

c) = 4 : 7/3 = 4 x 3/7 = 12/7 = 1 intreg 5/7

d) = 2/7 : 10/3 = 2/7 x 3/10 = 6/70 = 3/35

e) = 14/5 : 10/9 = 14/5 x 9/10 = 126/50 = 2,52

f) =  41/8 : 19/4 = 41/8 x 4/19 = 41/38

g) =  25/2 : 40/3 = 25/2 x 3/40 = 5/2 x 3/8 = 15/16

h) = 67/3 : 67/2 = 67/3 x 2/67  = 2/3 = > 0,(6)
