Пошаговое объяснение:


1) 5 + (-4.06) + (-3 1/4) = 5 - 4.06 - (3 1/4) = 0.94 - (3 1/4) = (94/100) - (3 25/100) = (-3 69/100)

2) 5 + (-3.18) + (-4 1/2) = 5 - (3 18/100) - (4 1/2) = 5 = (1 82/100) - (4 1/2) = (1 82/100) - (4 50/100) = (-3 32/100) = (-3 8/25)

3) -12 + (4 1/4) + (-5.8) = -12 + (4 1/4) - 5.8 = (-7 3/4) - (5 8/100) = (-7 75/100) - (5 8/100) = (-12 83/100)
