Question

Rezolva in Q+ urmatoarele ecuatii: a) (x-2/3) : 1/2 = 2/9 b)(x+0,0(5) ) : 0,(3) - 0,5 = 0,(3) Rapid dau coroana ,va rog

Answer 1

a)(x - 2/3) : 1/2 = 2/9
x-2/3 = 2/9x1/2 = 1/9
x =1/9 + 2/3 = 1/9 + 6/9 = 7/9
b) (x-0,0(5) ) : 3/9 = 3/9 + 5/10 = 30/90 + 45/90= 75/90
x-5/90= 75/90 x 3/9 = 25/10
x = 25/10 + 5/90 = 225/90 + 5/90 = 230/90 = 23/9
