Answer 1

Răspuns:

Explicație pas cu pas:

1.

1,96 : 0,07 = 196/100 : 7/100 = 196/100*100/7 = 196/7 = 28

(0,5)^2 = 0,25

28*0,25 = 28*25/100 = 28*1/4 = 7

5 1/3 = 16/3

7 - 16/3 = 21/3 - 16/3 = 5/3

(-1/3)^2 = 1/9

5/3 : 1/9 = 5/3*9 = 15

2.

(1/4)^2 = 1/16

(1/2)^3 = 1/8

1/16 : 1/8 = 1/16 *8 = 1/2

1/2 + 5/6 = 3/6 + 5/6 = 8/6 = 4/3

0,5 = 5/10 = 1/2

4/3 : 1/2 = 4/3 *2 = 8/3
