Answer 1

Răspuns

21/15 * 3/7 = 3/5(am simplificat 15 cu 3 si 21 cu 7)

21/15 : 7/5 = 21/15 * 5/7 = 3/3= 1

(7/9+4/3):(3.1/2  -  1.3/5)

(pe 4/3 il amplificam cu 3)

(7/9 + 3*4/3*3):(31/10/2 - 13/10/5)

3.1= 31/10

1.3= 13/10

(7+12/9):( 31/10 * 2 - 13/10 * 5)

(19/9) : (31/5 - 13/2)

(19/9) : (31*2/10 - 13*5/10)

(19/9) : (62/10 - 65/10)

(19/9) : (-3/10)

10/9 * 10/-3

100/-27

Sper ca e asa.
