Срочно! 1. Раскройте скобки и найдите значение выражения: 1,4-(0,7-3,2)+6(1 1\3 - 2 1\4) \ - нижнее подчёркивание Подробно!
1,4-(0,7-3,2)+6(1 1\3 - 2 1\4)=
1,4-0,7+3,2+8-13,5=12,6-14,2=-1,6
1.4 - ( 0.7 - 3.2) + 6 ( 1 1/3 - 2 1/4 ) = 4.4
0.7 - 3.2 = - 2.5
1.4 - ( - 2.5) = 1.4 + 2.5 = 3.9
1 1,3 - 2 1/4 = 4/3 - 5/4 = 16/12 - 15/12 = 1/12
6 * 1/12 = 6/12 = 1/2
3.9 + 1/2 = 3.9 + 0.5 = 4.4
