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

Nandini's house is 9/10 km from her school.She walked some distance and then took a bus for 1/2 km to reach the school.How far did she walk?

$\large\mapsto\boxed{ \sf \green{Answer}} \:$

$\mathtt{Total \: distance = \frac{9}{10}km}$

$\mathtt{Distance \: by \: bus = \frac{1}{2}km}$

$\mathtt{Distance \: walked = total \: Distance - Distance \: by \: bus = \frac{9}{10} - \frac{1}{2} }$

$\mathtt{L.c.m. \: of \: 10 \: and \: 2 \: is \: 10}$

$\mathtt{ \frac{9}{10} = \frac{9}{10} }$

$\mathtt{ \frac{1}{2} = \frac{5}{10} }$

$\mathtt{ \frac{9}{10} - \frac{5}{10} }$

$\mathtt{ = \frac{4}{10} = \frac{2}{5}kms}$
