a) 4x (1/4 - 0,18) :2/3=
7,2 : [(2 1/2 - 0,3)x 1/4=
b)1/3 x(2,4 + 3,5)=
6 1/4 + 2 1/2 x (5,2 - 1/5)=


a) x + 1/4 = 0,72
b) x - 2,3 =1 1/2
c) 3,1 - x = 1/4
d) 2,5 * x = 2
e) x : 0,1 = 1/4
f) 3,1 : x = 1/2



a) (2 1/2 + 0,25) * (1 1/11 - 8/11)=
b)(3 2/7 - 1/2) : (5 + 4/7 )=
c) 12 * (91/100 - 7/120 * 5)=
d) 2,228 * (4 1/5 + 3 1/2 - 7,7)=
