Ответ:
1)-17.14
2)0.64
3)-3.7/12
4)-1.1/4
Пошаговое объяснение:
1) 1)-13.4 * 0.6 = -8.4
2)-2.3 * 3.8 = -8.74
3)-8.4 + -8.74 = -17.14
2) 1) 2.8 - 5 = -3.2
2) -9.38 + 9.36 = -0.2
3) -3.2 * -0.2 = 0.64
3)1) 8/9 * -3 9/16 = -3
2) 4.5/6 * -7/58 = -7/12
3) -3 - (- 7/12) = -3.7/12
4)1) 4.7/8 - 7.1/6 = -2.7/24
2)2.1/20 - 0.45 = 3/5
3) -2.7/24 * 3/5 = -1.1/4
