13/75=13:75=0,17(3)

-7/8=-0.875

$3 \frac{8}{11} = \frac{3 \times 11 + 8}{11} = \frac{41}{11} = 3(72) \\ 5 \times \frac{12}{25} = \frac{5 \times 25 + 12}{25} = \frac{137}{25} = 5.48 \\ - 2 \times \frac{17}{55} = \frac{ - 2 \times 55 + 17}{55} = \frac{ - 110 + 17}{55} = \frac{ - 93}{55} = - 1.6(90)$
