Answer 1

Надеюсь, я правильно понял вопрос.

Ответы:

1) 4.5, 11.6, 19.78
2) 2.516, 1.25
3) 80.5, 2.72, 11.875
4) 49.22, 30.99, 9.5
5) 0.125, 0.026
6) 0.25, 0.04, 100

Пошаговое объяснение:

1) (7-2.5) = 4.5, (8.25+3.35) = 11.6, (10+9.78) = 19.78
2) (81.8+18.1)/(40.67) = 2.516, (0.97+0.28) = 1.25
3) (90-9.5) = 80.5, (2.66+0.06) = 2.72, (1.075+10.8) = 11.875
4) (28.88+20.34) = 49.22, (30.99) = 30.99, (4.9+4.6) = 9.5
5) (2.2-2.075) = 0.125, (1.08+0.28)/(36.6+5.9) = 0.026
6) (1.1-0.85) = 0.25, (0.023+0.017) = 0.04, (98.2+1.8) = 100
