Question

A $9m60cm$ long thread is cut into six pieces of equal length. Find the longest of each pieces.

Answer 1

Total length of thread $=9m+60cm$ $=(9+\frac{60}{100})m$

$=(9+\frac{3}{5})m=\frac{48}{5}m$; when it is cut, all the remaining pieces would measure $=\frac{48}{5\times 6}=\frac{8}{5}m=1.6$m

As all lengths are equal, longest piece would also measure $1.6$m.
