-14,3*6,6+5,7*(-1,4)= (23,42-54)*(-4,12+4.04= 5/9*(-3 6/7)-3 5/7)*3/52= (2 1/3 - 3 1/4)*(2 3/4-0.95)=

-14,3 * 6,6 + 5,7 * (-1,4) = -94,38 - 7,98 = -102,36;Ответ: -102,36.(23,42 - 54) * (-4,12 + 4,04) = -30,58 * (-0,08) = 2,4464;Ответ: 2,4464.(5/9 * (-3 6/7) - 3 5/7) * 3/52 = (5/9 * (-27/7) - 26/7) * 3/52 = (-15/7 - 26/7) * 3/52 = -41/7 * 3/52 = -123/364;Ответ: -123/364.(2 1/3 - 3 1/4) * (2 3/4 - 0,95) = (7/3 - 13/4) * (11/4 - 0,95) = (7 * 4 - 13 * 3)/12 * (11/4 - 95/100) = (28 - 39)/12 * (11/4 - 19/20) = -11/12 * (11 * 5 - 19 * 1)/20 = -11/12 * (55 - 19)/20 = -11/12 * 36/20 = -33/20 = -1 13/20.Ответ: -1 13/20.
