Add the three rope lengths:

1.5 m + 1.26 m + 1\( \frac{1}{2} \) m
= 1.5 + 1.26 + 1.5
= 4.26 m

Express 4.26 as a mixed number: 4\( \frac{26}{100} \).
Simplify the fraction: \( \frac{26}{100} = \frac{13}{50} \).

So the total length = 4\( \frac{13}{50} \) m.
In the form A\( \frac{b}{c} \): A = 4, b = 13, c = 50.

Final Answer: A = 4, b = 13, c = 50
