Answer 1

-19/53 + 1,7+1 intreg 1/35: 1 intreg  3/14 : -7,4 (6)+2,45:21/55 =
=-19/53 + 17/10+36/35: 17/14 : [-(746-74)/90]+245/100 ×55/21 =
=-19/53 + 17/10+36/35×14/17 : (-672/90)+7/4 ×11/3 =
=-19/53 + 17/10+36/5×2/17 : (-112/15)+77/12 =
=-19/53 + 17/10-72/85 × (-15/112)+77/12 =
=-19/53 + 17/10-9/17 × 3/14+77/12 =
=-19/53 + 17/10-27/238+77/12 =
=(-135660+643314-42930+2428195)/378420=
=2892919/378420
