Question

zapisz liczby w postaci ułamków zwykłch : -2,(7), -7,(8), -3,12(6)

Answer 1

-2,(7) = -2-(1/9*7) = -2-7/9 = -2i7/9 = -25/9

-7,(8) = -7-(1/9*8) = -7-8/9 = -7i8/9 = -71/9

-3,12(6) = -3-0,12-0,00(6) = -3-0,12-(1/9*1/100*6) = -3-12/100-6/900= -3-108/900-6/900 = -3-114/900 = -3i19/150 = -469/150
