a) (11/4 * 7-22) /11 +3/4= (19 1/4 -22) /11 -3/4= (-2 3/4) /11 -3/4= -11/44 -33/44= -44/44 = -1
b)(6/11 -1/3) / (3 4/6 - 2 3/6) * 11/4= (18/33-11/33) * 6/7 *11/4= 7/33*66/28=1/2

a) (10/15+3/15) /(0,4-0,5)+(3 2/17-4 6/13)(3/4-3/4)=13/15 *(-10)+0=-130/15= -8 10/15= -8 2/3
b)2/3-(0,8*3/4-4/5)*(-2/3)=2/3-(0,6-0,8)*(-2/3)=2/3-(-2/10)*(-2/3)=20/30-4/30=16/30=8/15
c)(2/6-3/6):(20/12-15/12)-(1/4-3/8 *8/5)= -1/6 : 5/12-(1/4-3/5)= -1/6*12/5 - (5/20-12/20)= -2/5-(-7/20)= -8/20+7/20= -1/20
