(1/4 -(1/4+1/9):1/9)*(2/3+7/15:(0,4 -1/6))= -15

1) 1/4+1/9=9/36+4/36=13/36
2) 13/36 : 1/9=13/36 * 9=13/4=3 1/4
3) 1/4 - 3 1/4= - 3
4) 0,4 -1/6=2/5 -1/6=12/30 - 5/30=7/30
5) 7/15 : 7/30=7/15 * 30/7=2
6) 2/3+2=5
7) - 3*5= - 15

.
(1,09 -0,29)*1 1/4 :((18,9 -16 13/20)*8/9)=0,5

1) 1,09-0,29=0,8
2) 0,8*1 1/4=4/5 * 5/4=1
3) 18,9 -16 13/20=18 9/10 - 16 13/20=18 18/20 - 16 13/20=2 5/20=2 1/4
4) 2 1/4 * 8/9=9/4 * 8/9=2
5) 1 : 2=1/2=0,5

1)(-6):(-2)+(-8):4-(-2)= 2)-6*4-84:(-3.8+1.7)= 3)(-8):(-4)-(-6):3-(-3)= 4)(-6+6....
