Answer 2

Answer:

7.5m

Step-by-step explanation:

$\frac{11}{5} + \frac{23}{10 } \\ = \frac{22 + 23}{10} \\ = \frac{45}{10}$

total length of the two pieces of rope = 45/10 m

$\frac{12}{1} - \frac{45}{10} \\ = \frac{120 - 45}{10} \\ = \frac{75}{10 } = \frac{15}{2}$

the length of the remaining rope = 15/2m or 7.5 m
