Question

[ 1,(3)x/2 - 2* 1/4] : 0,6 = x/9

Answer 1

1,(3)=(9+3)/9 = 12/9= simplificam cu 3 = 4/3
2× 1/4=2/4=1/2

(4x/6 - 1/2) : 6/10 = x/9   aducem la acelasi numitor in paranteza ...6
(4x/6 - 3/6) × 10/6 = x/9
40x/36 - 30/36 = x/9   aducem la acelasi numitor 36 si eliminam numitorul 36
40x - 30 = 4x     separam variabila
40x - 4x = 30
36x=30
x=30/36= simplificam cu 6 = 5/6
x = 5/6
