Question

From a rope $10\frac{1}{2}m$ long, $4\frac{5}{8}m$ is cut off. Find the length of the remaining rope.

Answer 1

Initial length of rope $={10}^{1/2}m=\frac{21}{2}m$

Length cut $=4\frac{5}{8}m=\frac{31}{8}m$

Length of remaining $=\frac{21}{2}-\frac{37}{8}$

$=(\frac{84}{8}-\frac{37}{8})$

$=\left(\frac{47}{8}\right)m$

$Lengthofremainingrope=5\frac{7}{8}m$
