Complete step by step solution:
Total length of cloth that Mohini has= m
Length of cloth required for each shirt= m cm

Using unit method,
cm m
cm m m

Number of shirts=n=
Since the number of shirts cannot be a fractional quantity, it must be a natural/whole number.
Therefore,
Length of cloth left=Total length of cloth-length of cloth required for
Length of cloth required for
=
Length of cloth left=
Conversion of unit of measurements;
Length of cloth left is
