Question

Reshma drew a line that was $2\frac{4}{8}$ $cm$ long. Then, she drew a second line that was $7\frac{3}{4}$

$cm$ long. What is the total length of the line that is drawn by Reshma?

Answer 1

Total length $=$ $2\frac{4}{8}+7\frac{3}{4}$

$=\frac{20}{8}+\frac{31}{4}$

Take the LCM of $8and4$ i.e. $8$

$=\frac{20+62}{8}=\frac{82}{8}m$

Hence , the total length is $\frac{82}{8}m$.
