$\large\mapsto\boxed{ \sf \red{Question}} \:$

$\pink{\mathtt{Roma \: gave \: a \: wooden \: board \: of \: length \: 150 \frac{1}{4} \: cm\: to \: a \: carpenter \: for \: making \: a \: shelf.the \: carpenter \: sawal \: off \: a \: piece \: of \: 40 \frac{1}{5} \: cm \: from \: it. \: what \: is \: the \: length \: of \: the \: remaining \: piece.}}$

$\large\mapsto\boxed{ \sf \green{Solution}}$

$\pink{ \mathtt{Total \: length \: of \: the \: wooden \: board \: = 150 \frac{1}{5} }}$

$\pink{ \mathtt{Length \: sawad \: off \: by \: the \: carpenter \: = 40 \frac{1}{5} }}$

$\pink{ \mathtt{The \: length \: of \: the \: remaining \: piece \: = 150 \frac{1}{4} - 40 \frac{1}{5} }}$

$\pink{ \mathtt{Changing \: into \: improper \: fraction : 150 \frac{1}{4} = \frac{601}{4}; \: 40 \frac{1}{5} = \frac{201}{5} }}$

$\pink{ \mathtt{L.C.M. \: of \: 4 \: and \: 5 \: is \: 20.}}$

$\pink{ \mathtt{ \frac{601 \times 5}{4 \times 5} = \frac{3005}{20}; \frac{201 \times 4}{5 \times 4} = \frac{804}{20}}}$

$\pink{ \mathtt{ \frac{3005}{20} - \frac{804}{20} = \frac{2201}{20} = 110 \frac{1}{20} }}$

$\pink{ \mathtt{The \: length \: of \: the \: remaining \: piece \: is 110 \frac{1}{2} cm}}$
