7/18-(21/5+8/9)+17/15= -3.56666666667
26/75-76/30-(+7/6)-2= -5.353333333
1)1/5 - {3/4 - [1/8 - (1/2 - 1/3) ] }=1/5-{3/4-[1/8-1/2 +1/3]}=1/5-{3/4- 1/8+ 1/2 -1/3}
=1/5-3/4+1/8-1/2+1/3 =24-30+15-60+40 /120 =-11/120
(2+2/3÷1/5 ×4/7)÷(47/63÷2/5)=(2+2/3 ÷4/35)÷(47/63 ×5/2)=
(2+2/3 × 35/4)÷(235/126) =(2+70/12)÷(235/126)=(24+70 /12)÷(235/126)=
94/12 × 126/235 = 2/2 × 21/5 = 42/10
(2 + 2/5) ÷ (18/5) - 7/9 ÷ 4/3 =( 10+2 /5)÷(18/5)-7/9×3/4 =12/5÷18/5 -21/36 =12/5 ×5/18 -21/36 = 2/3-21/36= 24-21 /36 =3/36 =1/12
