Answer 1

Răspuns:

A 19/25- 2/4+7/100

19/25 ( x 4) - 2/4 ( x25) +7/100

76/100-50/100+7/100 = 33/100

B 2 5/6 + 4 3/4

17/6 + 19 /4

17/ 6 ( x 2) + 19/4 ( x3)

34/12 + 57/12 = 91/12

E 11/70 - 1/20+3/ 14

11/70 ( x2) - 1/20( x7) + 3/14 ( 10)

22/140 - 7/ 140 + 30/140

45/140 ( :5)

9/28

F. 2. 2/3 + 6 1/2

8/3 + 13/2

8/3 ( x2) + 13/2 ( x3)

16/6+39/6

55/6

Success!!
