1.1 (3,04 : 1/30 - 16,03 : 7/20) * 1/5 + 0,072 * 1/3 = 9,104.

а) 3,04 : 1/30 = 3,04 * 30 = 91,2;

б) 16,03 : 7/20 = 16,03 : 0,35 = 45,8;

в) 91,2 - 45,8 = 45,4;

г) 45,4 * 1/5 = 45,4 * 0,2 = 9,08;

д) 0,072 * 1/3 = 0,072/3 = 0,024;

е) 9,08 + 0,024 = 9,104.

1.2 (-1,7 + 3,64 : (-1,4)) : (-0,001) * (-0,4) = -1720.

а) 3,64 : (-1,4) = -2,6;

б) -1,7 - 2,6 = -4,3;

в) -4,3 : (-0,001) = 4300;

г) 4300 * (-0,4) = -1720.

2.1  2,9х - 4,7d + 4,3 - 3,4c + 3,1d =

= 2,9x - 3,4c - 1,6d + 4,3.
