Answer 1

Answer:

$\frac{131}{30}$m will be left.

Step-by-step explanation:$\frac{131}{30} -\frac{77}{6} = -\frac{127}{15}$

Total length of pieces of ribbon: $\frac{17}{2} +\frac{13}{3} =\frac{51}{6} +\frac{26}{6} =\frac{77}{6}$

Length left after using ribbons: $\frac{86}{5} -\frac{77}{6} =\frac{516}{30} -\frac{385}{30} =\frac{131}{30}$

The tailor cannot stitch one more dress because:

$\frac{131}{30} -\frac{77}{6} =-\frac{127}{15}$.
