Answer 2

$\displaystyle\bf\\1)\\\\3\frac{17}{36} :\frac{2}{9} =\frac{125}{36} \cdot\frac{9}{2} =\frac{125}{8} \\\\\\2)\\\\5\frac{1}{17} :\frac{2}{9} =\frac{86}{17} \cdot\frac{9}{2} =\frac{387}{17} \\\\\\3)\frac{125}{8}-\frac{387}{17}=\frac{125\cdot 17-387\cdot 8}{8\cdot 17} =\frac{2125-3096}{136} =-\frac{971}{136} \\\\\\4)\\\\\frac{3}{26} \cdot4\frac{1}{3} =\frac{3}{26} \cdot\frac{13}{3} =\frac{1}{2}$

$\displaystyle\bf\\5)\\\\-\frac{971}{136} -\frac{1}{2} =-\frac{971+68}{136} =-\frac{1039}{136} =-7\frac{87}{136}$
