Q.2 Sarita bought \(\frac{2}{5} \) metre of ribbon and Lalita \(\frac{3}{4} \) metre of ribbon. What is the total length of the ribbon they bought?

Length of ribbon bought by Sarita = \(\frac{2}{5} \) metre
Length of ribbon bought by Lalita = \(\frac{3}{4} \) metre
\(\therefore \) Length of ribbon bought by Sarita and Lalita \(\frac{2}{5} + \frac{3}{4} \)
LCM of 5 and 4 = 20
\(\frac{2×4}{5×4} + \frac{3×5}{4×5} \)
= \(\frac{8}{20} + \frac{15}{20} \)
= \(\frac{23}{20} \) = \(1\frac{3}{20} \) meter
