Пошаговое объяснение:
1.
1) -5 3/4 * 8 = - 23/4 * 8/1 = - (23*2)/1 = - 46
2) 7 2/3 * (-9) = 23/3 * -9/1 = - (23*3)/1 = - 69
3) 15 * (-4 3/5) = 15/1 * (-23/5) = -(3*23)/1 = - 69
4) -11 7/9 * (-18) = -106/9 * (-18/1) = (106*2)/1 = 212
5) -22 * 4 8/11 = -22/1 * 52/11 = -(2*52)/1 = -104
6) -12 * (-25 1/3) = -12/1 * (-76/3) = (4*76)/1 = 304
