0,7 (-10)^3-20=0,7*(-1000)-20=
-700-20=-720
...............................=1/5
1) 3/8 - 7/18=27/72 - 28/72= - 1/72
2) - 1/72 *3,6= - 1/72 * 36/10= - 1/20
3) 5/18+2/27=15/54+4/54=19/54
4) 19/54 : 1 11/27=19/54 : 38/27=19/54 * 27/38=1/4
5) - 1/20+1/4= - 1/20+5/20=4/20=1/5
2-х/4=-6
-х/4=-6-2=-8
х=8*4=32
