Answer 1

Răspuns:

Explicație pas cu pas:

a)

5 - numaratorul (cel de sus)  îl facem din ce nr vrem noi ( 1+2+2) , (1+1+3) , ( 0+5 )

numitorul 6 ....il lasam asa (cel de jos)

-

La diferenta ......numaratorul (cel de sus ) trebuie sa -l obtinem dintr-o scadere pe care o vrem noi ( 9-4=5) , (8-3=5 ) (7-2=5 )

Numitorul ramane acelasi (6)

La fel si la celelalte

-

a)

suma :

1/6+2/6+2/6=5/6

1/6+1/6+3/6=5/6

0+5/6=5/6

-

diferenta :

9/6-4/6=5/6

8/6-3/6=5/6

7/6-2/6=5/6

-

b)

suma:

30/54+5/34+2/54= 37/54

20/54+17/54=37/54

10/54+27/54=37/54

-

diferenta :

49/54-12/54=37/54

60/54-23/54=37/54

45/54-8/54=37/54

-

c)

suma :

100/324+5/324+4/324=109/324

80/324+20/324+9/324=109/324

25/324+70/324+34/324= 109/324

diferenta :

200/324-91/324=109/324

143/324-34/324= 109/324

110/324-1/324=109/324
