Answer 1

$( 5\frac{2}{3} -7 \frac{1}{39} ): \frac{73}{78} =( \frac{17}{3} -\frac{274}{39} )*\frac{78}{73} =( \frac{221}{39} -\frac{274}{39} )*\frac{78}{73} =-\frac{53}{39} *\frac{78}{73} =-\frac{106}{73}$$=-1\frac{33}{73}$

Answer 2

(5 2/3 - 7 1/39) : 73/78 = (5 26/39 - 7 1/39) : 73/78 = - 1 14/39 : 73/78 = - 53/39 : 73/78 = - 53/39 * 78/73 = - 106/73 = - 1 33/73
