Răspuns

Explicație pas cu pas:

a)   7 / 8 - 3 / 8 = 4 / 8 = ( 4 : 4 ) / ( 8 : 4 ) = 1 / 2

b)   9 / 16 - 1 / 16 = 8 / 16 = ( 8 : 8 ) / ( 16 : 8 ) = 1 / 2

c)   11 / 12 - 7 / 12 = 4 / 12 = ( 4 : 4 ) / ( 12 : 4 ) = 1 / 3

d)   11 / 5 - 6 / 5 = 5 / 5 = 1

11 / 5 - 6 / 11 = 121 / 55 - 30 / 55 = 91 / 55 =1 intreg si 36 / 55 ≅ 1,65
