(-3.9 - 2.6) - (6/36 - 4/7) + 6.1 = -6.5 - (1/6 - 4/7) + 6.1 = -6.5 - (7/42 - 24/42) + 6.1 = -6.5 - (-17/42) + 6.1 = -6.5 + 17/42 + 6.1 = -6.5 + 0.4048 + 6.1 = -6.5 + 0.4048 + 6.1 = -6.5 + 6.5048 = 0.0048
Таким образом, значение выражения (-3.9 - 2.6) - (6/36 - 4/7) + 6.1 равно 0.0048.
(-3.9 - 2.6) - (6/36 - 4/7) + 6.1
= -6.5 - (1/6 - 4/7) + 6.1
= -6.5 - (7/42 - 24/42) + 6.1
= -6.5 - (-17/42) + 6.1
= -6.5 + 17/42 + 6.1
= -6.5 + 0.4048 + 6.1
= -6.5 + 0.4048 + 6.1
= -6.5 + 6.5048
= 0.0048
Таким образом, значение выражения (-3.9 - 2.6) - (6/36 - 4/7) + 6.1 равно 0.0048.
