Пошаговое объяснение:
а) = -114 + 24 * (-4) + 480 = -114 - 96 + 480 = 270
б) = ( (-10/3) + (17/6) ) * ( (-77/9) + (65/9) ) = ( -1/2) * ( -4/3) = 2/3
в) = (4/3) * (-3/4) + (2 1/7) * (7/5) = -1 + (15/7) * (7/5) = -1 + 3 = 2
г) = (5/6) * ( ( -153/10 ) - ( 243/10 ) * (5/9) ) = (5/6) * ( (-153/10) - (27/2)) = (5/6) * (-144/5) = -24
