Question

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

Answer 1

Length of rope$=10\frac{1}{2}$m

Length of cut off rope$=4\frac{5}{8}$m

Remaining rope$=10\frac{1}{2}-4\frac{5}{8}$m

$=\frac{21}{2}-\frac{37}{8}$m

$=\frac{21\times 4-37}{8}$m

$=\frac{84-37}{8}=\frac{47}{2}=5\frac{7}{8}$m
