Answer :

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
